PET/CT(FDG)検査とは

がんなどの病気を見つける画像検査です。「がん細胞が正常細胞に比べて何倍も多くブドウ糖を取り込む」という仕組みを利用し、ブドウ糖に似た検査薬（FDG）を体内に注射して、全身のがんの有無を調べます。

PET/CT検査の利点と欠点

利点と欠点

• ✔　早期発見
• ✔　全身を一度で調べて、多くのがんを発見できること
• ✔　がんの種類によって通常のレントゲンやCT、MRI検査より

　　正確な診断がつく可能性が高い
✔　安全で身体的負担が少ない

病変の種類・部位・大きさによっては評価が難しく、炎症や正常臓器にもFDGが集まることがあり、精度は100%ではありません。重度の糖尿病があると画像は不鮮明になることが多く、当日の血糖値が200mg/dl以上ある場合は検査を延期することがございます。

見つけやすいがん

頭頚部・甲状腺・肺・乳房・食道・大腸・膵臓・子宮・卵巣などのがん。悪性リンパ腫、悪性黒色腫、骨腫瘍など

見つかりにくいがん

FDGが集まりにくい胃や肝臓・胆道がんや正常でもFDGが集まりやすい脳・心臓・腎臓・尿管・膀胱・前立腺などのがん

What is a PET/CT (FDG) Scan?

　A PET/CT scan is a type of imaging test that can detect cancers and other diseases. Since cancer cells absorb much more glucose than normal cells, a glucose-like tracer (FDG) is injected into the body to detect the entire body for the presence of cancers.

PET/CT Examination and Its Advantages

Advantages and Disadvantages

✔　Early detection is possible.
✔　It allows for a comprehensive examination of the entire body in a single test, detecting many types of cancer.
✔　Depending on the type of cancer, it can provide a more accurate diagnosis compared to regular X-rays, CT scans, or MRI scans.
✔　It is safe and imposes minimal physical burden on the examinee.

However, depending on the type, location, and size of the lesions, it can be very difficult to make an accurate assessment. FDG can accumulate in inflamed areas or normal organs, so the accuracy is not always 100%. In patients with severe diabetes, the images often become unclear, and if the blood glucose level is 200 mg/dL or higher on the day of the examination, it may need to be postponed.

Cancers that are Easily Detected

　Cancers of the head and neck, thyroid, lung, breast, esophagus, colon, pancreas, uterus, and ovaries. Malignant lymphoma, malignant melanoma, and bone tumors.

Cancers that are Difficult to Detect

　Cancers of the stomach, liver, and bile ducts where FDG accumulation is low, as well as cancers of the brain, heart, kidneys, ureters, bladder, and prostate where FDG accumulation is high even under normal conditions.

PET/CT Scans are Recommended for:

✔　Those who want early detection of cancer
✔　Those with a family history of cancer

Not Suitable for:

✔　Individuals with extreme claustrophobia
✔　Those who have difficulty walking independently
✔　Those who have trouble using the toilet by themselves
✔　Individuals with cognitive impairment
✔　Those who have had an epileptic seizure within the past year
✔　Pregnant women or those who might be pregnant
✔　Breastfeeding women

FDG Tracer Injection

　In the examination room, FDG tracer will be injected into a vein in your arm.

Resting

　After the injection, you will need to rest in a designated waiting area for about 60 minutes while the tracer spreads throughout your body. During this time, you cannot use your mobile phone or read books. If you are unable to remain still, the examination may not be possible.

Both the examination room and the waiting area are designed
with a calming mint green theme.

Scanning

　The imaging will be done using a PET/CT scanner, which combines a PET camera and a CT scanner. The scanning time is approximately 30 minutes.

PET/CT(Discovery IQ)

Resting

　After the scan, you will need to wait in a designated area for about 30 minutes until the radiation from the FDG in your body decreases.

Payment

　After all the examinations are completed, the coordinator will guide you to the Accounts desk for your payment.

Q&A

About Examinations

Q : What is a PET scan?
A :
In a PET scan, a radioactive drug called a positron emitter is injected into the body and a PET scanner is used to take pictures of the radiation emitted from inside the body. Unlike CT or MRI scans, which show structural changes such as organ shapes, PET scans show functional changes such as organ metabolism (cell activity).

Q : Does a PET scan eliminate the need for other tests?
A :
A PET scan does not detect all types of cancer. Some cancers can be difficult to detect. Depending on the disease, it may be used in combination with blood tests, endoscopy, or ultrasound to make a more accurate diagnosis.

Q : Can all types of cancers be detected with a PET scan?
A :
The effectiveness of PET scans varies depending on the type of cancer. The more difficult detecting very small cancers (less than 1 cm) becomes, the smaller they are. In addition, PET scans can detect benign conditions, such as inflammation, because the tracer can also be taken up by non-cancerous lesions. Not all abnormalities detected are malignant, and it can be difficult to distinguish between benign and malignant findings. A biopsy is often required to make a definitive cancer diagnosis.

Q : Is the examination painful?
A :
There may be some pain when the FDG is injected, but the examination itself is not painful. Sometimes, due to nervousness during the injection, a vasovagal reaction (such as a drop in blood pressure) can occur.

Q : How long does the PET scan take?
A :
After an explanation of the procedure and a brief interview, you will change into a gown and receive the tracer injection. After the injection, you will rest for about an hour before the scan, which takes about 25 minutes. After the scan, there is a waiting period of about 30 minutes. If necessary, a second scan may be performed, which takes about 10 minutes. The entire process, from check-in to completion, takes about three hours.

Q : Can I move my body during the examination?
A :
You cannot move your body during the examination.

Q : I have claustrophobia. Can I stop the examination halfway through?
A :
If you have severe claustrophobia, you may not be able to undergo the examination. Please inform us in advance. The examination involves entering a tunnel-like device with a diameter of about 70 cm for approximately 30 minutes.

Q : I'm concerned about radiation exposure.
A :
The amount of radiation exposure from a PET/CT scan is approximately equivalent to 1-4 times that of a barium swallow test, which is a low dose and not at a level that should cause concern. The FDG will go out of your body in several hours, so avoid close contact with infants, pregnant women, and breastfeeding women for several hours after the examination.

For More Information (Radiation Dose)
　The radiation exposure from the FDG tracer used in PET scans is considered to be less than that from a stomach X-ray examination, at approximately 3.5 mSv. This is about one-fifth to one-tenth of the radiation exposure from a full-body CT scan. While PET/CT scans include radiation exposure from the CT component, there is no risk of radiation damage to the body.
　For reference: Stomach barium X-ray: 4 mSv, Chest CT scan: 6 mSv, PET/CT: 10 mSv (according to data from Saku Central Hospital).
　The administered tracer is very short-lived and is excreted through the urine, so it is mostly eliminated from the body within one day.

Q : How can I obtain more accurate test results?
A :
Excess tracer is excreted in the urine. Drinking plenty of sugar-free beverages, such as tea or water, before the test can help produce clearer images and reduce radiation exposure. For examinees with diabetes, it may be difficult to obtain clear images necessary for diagnosis if fasting blood glucose exceeds 200.

For Women

Q : Menstruation
A :
For women with menstrual periods, the timing of the test may affect the clarity of certain areas. Please contact us for further details.

Q : Breastfeeding
A :
Try to avoid breastfeeding immediately after the test. **Breastfeeding is prohibited for 12 hours after the tracer injection.** Consider expressing and storing milk before the test.

Q : Pregnancy
A :
As with other radiological tests, we do not recommend PET scans during pregnancy due
to the potential for radiation exposure to the fetus.

Before Examination

Q : Are there any precautions I should take from the day before the examination?
A :
From the day before the examination until the examination is completed, avoid strenuous exercise and physical labor, and similar activities. Excessive exercise may cause accumulation in the muscles.

Q : Can I eat and drink on the day of the examination?
A :
Please finish your meal at least 6 hours before your appointment time. Eating within 6 hours of your appointment time will generate inaccurate results, and the examination cannot be performed. This includes candy, gum, fruit, soup, and juice. There are no restrictions on sugar-free tea or water.

Q : Can I take my usual medication?
A :
If you have diabetes, stop taking your diabetes medication and insulin 6 hours before your appointment time. Other medications prescribed by your physician can be taken as usual.

After Examination

Q : Are there any precautions after the test?
A :
After a PET scan, to minimize radiation exposure to others, please avoid crowded places as much as possible. Also, try to limit contact with infants and pregnant women as much as possible.

Other Information

Q : Do other tests interfere with the PET Scan?
A :
Vaccinations
　Vaccinations can accumulate in the lymph nodes and affect the images. Please schedule your PET scan beyond at least two weeks after receiving a vaccination.
Barium Tests
　Barium can interfere with CT images. Please schedule your PET scan beyond at least one week after a barium test.
Nuclear Medicine Tests
　Consider the effects of residual radiation in your body. It is recommended that you have the PET scan first and then schedule the nuclear medicine test on a different day.
Bone Density Tests
　Consider the effects of residual radiation in your body. It is recommended that you have the bone density test first
Contrast-enhanced CT Scans
　Residual contrast material may cause higher readings. Please schedule your PET scan the day before or after your contrast-enhanced CT scan.
Endoscopy
　Inflammation at the test site may cause FDG uptake. If you have an endoscopy on the same day, we will provide a reading report that takes this into account
Bronchoscopy
　Please schedule your PET scan beyond at least one week after a bronchoscopy.
Biopsy
　Please schedule your PET scan beyond at least one week after a biopsy.

Q : I don't speak Japanese. Can I still have the test?
A :
If you do not speak or read Japanese, please have someone who does accompany you.

If you are eligible for the following, please read the relevant sections carefully.

Diabetic Patients:
➤ If your blood glucose level is 200 mg/dL or over before the test, the test may not be conducted.
➤  Please remove your insulin pump and continuous glucose monitor before the test, and bring new ones with you. Confirm with your diabetes specialist whether it is safe to remove these devices for approximately one hour.

Home Oxygen Therapy:
➤ Please use your own oxygen cylinder. Ensure you bring enough oxygen to last until you return home.

Implanted Medical Devices:
➤ If you have a pacemaker or ICD, please make sure to inform us in advance.
➤ Please bring your pacemaker and ICD (Implantable Cardioverter Defibrillator) identification certificate.

什么是PET/CT(FDG)检查

早期诊断并鉴别肿瘤的成像检查。
利用「癌细胞凝聚葡萄糖会比正常细胞多出好几倍」的原理，向体内注射性质类似葡萄糖的显像剂（FDG），来筛查全身肿瘤（癌症）。

PET/CT检查的利弊

PET/CT检查利弊

但是根据病变种类·部位·大小有可能无法进行评估，并且FDG有时也会凝聚在炎症发生部位或正常器官，因次检查精确度无法达到100%。重度糖尿病患者成像不清晰的情况较多，如果检查当天的血糖值超过200mg/dl，检查可能需要延期。

容易发现的肿瘤

头颈部·甲状腺·肺·乳房·食道·大肠·胰腺·子宫·卵巢等癌症。
恶性淋巴瘤，恶性黑素瘤，骨肿瘤等。

不易发现的肿瘤

FDG药剂不容易凝聚的胃，肝脏·胆管的癌症。
脑·心脏·肾脏·输尿管·膀胱·前列腺等癌症，因为这些器官在正常情况下也容易凝聚FDG药剂。

Q&A

关于检查

Q :PET扫描是一种什么样的检查？
A :
向体内注射一种发射放射线的正电子显像剂，用PET设备拍摄体内放出的放射线量。与CT或MRI拍摄形态变化（器官的形状）的检查不同，该检查是将器官的代谢等功能变化作为成像来检查。

Q : 做PET检查，就不用做其他检查吗？
A :
PET检查并不能检查出所有癌症。其中也有较难发现的癌症。
根据疾病，并用血液化验，内窥镜检查，超声波检查等，诊断精度会更高。

Q : 可以检查出所有肿瘤吗？
A :
根据肿瘤的种类，PET检查有擅长不擅长。大小不满1cm的小肿瘤，很难被发现。除了癌症以外，炎症等良性病变，也有可能聚集药物并在PET成像中显现。
此外，并非所有发现的疾病都是恶性，也有无法判断良性还是恶性的可能性。确诊癌症很多情况需要采集细胞或组织来做病理学检查（活检）。

Q : 检查伴随疼痛吗？
A :
显像剂静脉注射时会痛，除此之外没有任何疼痛。拍摄期间，需要平躺在检查台上大约25分钟左右。会尽量让您保持舒适的姿势。
※注射时，过度紧张，有可能发生血压下降等迷走神经反射。检查之前会做说明。

Q :检查需要多长时间？
A :
检查说明还有问诊之后，换成检查服，注射显像剂。注射后需要安静等候1个小时，之后会拍摄25分中左右。拍摄完毕，在休息室等待30分钟，就可以结束。如果有需要会拍第二次（10分钟左右）。从检查受理到结束为止，全程大概需要3个小时。

Q :检查过程中，身体可以活动吗？
A : 
检查过程中，不可以活动身体。请听好技师指令。

Q : 我有封闭恐惧症。检查途中发作，可以叫停吗？
A :
如果您的封闭恐惧症较严重，可能无法接受检查。请您务必告知我们。该检查需要躺在直径大约70cm的隧道式装置里面，并且持续30分钟左右。

Q :我担心核辐射。
A :
PET/CT（FDG）的辐射是微量的，相当于胃肠道钡餐透视的1到4次左右的辐射量，所以不必担心发生辐射性损伤。FDG显像剂会在几个小时内从体内消失，因此在检查后几个小时之内，不要接触，婴幼儿·孕妇·哺乳期女性。
关于辐射量具体是
FDG显像剂的辐射量是3.5mSv（毫西弗）左右，低于胃肠道钡餐透视的辐射量，相当于全身CT的十分之一到五分之一。PET/CT检查的总辐射量是FDG显像剂加CT检查的辐射量，但是也不会对身体造成辐射性损伤。
※胃肠道钡餐透视：4mSv、胸部CT检查：6mSv、PET/CT：10mSv（引用自佐久医疗中心的资料）
　注射体内的显像剂药物寿命非常短，会通过小便排出体外，大概1天左右时间基本上会从体内消失。

Q :为了做好检查？
A :
多余的显像剂药物会通过尿排出体外。检查前尽量多喝水（只限纯净水，果味水除外），影像会更鲜明，也会降低辐射量。
糖尿病患者，如果检查当天的血糖值超过200mg/dl，很难获得清晰的影像，也可能影响下诊断。

关于女性

Q : 关于月经
A :
在经期，根据检查时间某些部位可能难以诊断，如果检查日期碰上经期，请提前告诉我们。

Q : 关于哺乳
A :
检查之后请暂停哺乳。从药物注射起12个小时之内，请不要哺乳。请在检查之前做好吸乳等准备。

Q : 孕期
A :
与其他核医学检查一样，孕期不适宜做PET/CT检查。因为会对胎儿有辐射。

检查前

Q : 前一天开始有什么要注意的吗？
A :
检查前一天到检查结束为止请避免剧烈运动且不要过度操劳。过度的运动会使肌肉容易聚集药物。

Q : 检查当天，可以吃饭吗？
A :
检查前6个小时需要禁食。如果检查前6个小时之内吃过东西，会导致检查结果不准，所以无法接受检查。糖，口香糖，水果，汤汁，果汁，饮料，牛奶，酒等也要禁饮6个小时。只可以饮用纯净水（果味水除外）。

Q : 平常吃的药，可以正常服用吗？
A :
糖尿病患者需在检查前6个小时停用糖尿病药物和胰岛素。此外，平时服用的处方药可以照常服用。

检查后

Q : 检查结束后，有什么注意事项吗？
A :
PET检查后，为了防止体内放出的放射线对周围人的辐射，请尽量避开人多的地方。
检查结束当天，请避免接触婴幼儿，孕产妇及哺乳期女性。

其他

Q : 其他检查，会对PET/CT有影响吗？
A :
疫苗
　药物聚集在淋巴结，影响成像。请从疫苗接种日间隔两周以上，再预约PET/CT检查。
胃肠道钡餐透视
　影响CT成像。请间隔1周以上，再预约。
核医学检查
　需要考虑残留在体内的辐射的影响。请先进行PET检查，然后改天预约核医学检查。
骨密度检查
　要考虑残留在体内的辐射的影响。请先进行骨密度检查。
造影CT检查
　如果造影剂残留在体内的状况下，进行PET/CT检查，指标容易偏高。请在造影CT检查前一天为止或者检查第二天之后再预约PET/CT检查。
内窥镜检查
　内窥镜的检查部位如果有炎症，将容易聚集FDG药剂。
　※如果同一天有做胃镜，会考虑胃镜检查带来的影响的基础上，做读影报告。
支气管镜检查
　检查部位如果有炎症，将容易聚集FDG药剂。请间隔1周以上再做PET/CT检查。
活检
　检查部位如果有炎症，将容易聚集FDG药剂。请间隔1周以上再做PET/CT检查。

Q :不会说日语，可以接受检查吗？
A :
日语读写困难者，需要会日语的人陪同做检查。若您找不到陪同做口译的人，请提前咨询我们。
本院也可以提供体检口译服务（有偿），但是口译人员人数有限，请务必提前联系。
