September 2,2019 Update
Nuclear medicine refers to the field of diagnosis and treatment of diseases by administering a drug (radioactive agent) with a small amount of a radioactive isotope (radioisotope: RI) as a marker.
When the radioactive agent is administered to the body, it is taken in by a specific organ, and the radiation energy is emitted there. The radiation is captured with a special camera called a "Gamma Camera (scinticamera)." In this manner, a characteristic of a nuclear medical examination is that it can create an image of the workings of the organ and the chemical changes, without any pain.
|Equipment||Mainly used for examination|
|Discovery NM630 (GE)||Cerebral blood flow scintigraphy, myocardial perfusion scintigraphy, bone scintigraphy, etc.|
|PRISM-AXIS (Shimadzu Corporation)||Lung perfusion scintigraphy, sentinel lymph node scintigraphy, myocardial perfusion scintigraphy, etc.|
|Biograph16TP (SIEMENS)||Systemic tumor sugar metabolism PET/CT, etc.|
Nuclear medicine examination and MR examination reception
The nuclear medicine examination requires a waiting time after administering the radioactive agent for the agent to gather in the desired organ.
The time varies depending on the type of examination and the radioactive agent. The times required for the primary examinations and the duration of the imaging are shown below.
|Examination name||Radioactive agent||Purpose||Waiting time||Imaging time|
|Bone scintigraphy||Tc-99m MDP etc.||Bone metastasis bone tumors etc.||After administration about 3 hours||About 30 minutes|
|Gallium scintigraphy||Ga-67 citate||Systemic search for tumors and inflammation||After administration, about 3 days||About 30 minutes to 45 minutes|
|Myocardial perfusion scintigraphy||Tl-201 Cl||Myocardial blood flow distribution||After administration, 10 minutes and 3 hours (will be imaged twice)||About 20 minutes|
|Cerebral blood flow scintigraphy||Tc-99m ECD||Evaluation of cerebral blood flow distribution||There is no waiting time||About 30 minutes|
|Systemic tumor sugar metabolism PET/CT||F-18 FDG||Systemic tumor sugar metabolism||After administration about 1 hour, and after imaging 40 minutes||Approx. 30 minutes(about 3 hours including waiting time)|
* The time and duration of the imaging may vary depending on the type of examination and the directions from the doctor.
|Bone scintigraphy||Tc-99m MDP, etc.||Urination just before imaging|
|Gallium scintigraphy||Ga-67 citate||Take a laxative the day before the imaging and defecate before imaging|
|Myocardial perfusion scintigraphy||Tl-201 Cl||Prohibition of food and drink, except for water, from the morning of examination day|
|Cerebral blood flow scintigraphy||Tc-99m ECD||None|
|Systemic tumor sugar metabolism PET/CT||F-18 FDG||Fast for more than 5 hours before the examination
Please refrain from strenuous exercise from the day before the inspection.
* The pre-treatment may vary depending on the type of examination and the directions from the attending doctor.
Please inform the attending doctor at the time of the reservation if any of the following apply to you.
