liver

After 30-60 minutes, the radiopharmaceutical maybe visualized in the GIT if the result would be normal in Dynamic Imaging study of what body organ?

Capsule

A covering of the spleen which is fibro-elastic tissue and occasional smooth muscle cells.

IV injection of 250 microcurie of Iodine 131 labeled Rose Bengal is administered and after an hour, anterior images are taken every 10 minutes. Images are taken again every 6 hours and 24 hours if it is necessary.

Describe the procedure in Dynamic imaging of the Liver & Spleen. (ESSAY)

Technetium 99m labeled pyrophosphates

"Hot Spot" imaging results by using this radiopharmaceutical, which is then used to show blood flow to the different organs of the body.

3-6 millicurie

In Static imaging of the liver & spleen, Technetium 99m-Sulfur Colloid is injected to the patient for how many millicurie?

Static procedure of the heart is repeated after 3-4 hours post administration and post stress to determine if Thallium is redistributed under non-stress condition.

What is the purpose of repeating images in Static procedure for the heart after 3-4 hours post administration and post-stress? (ESSAY)

E. 3&4

Technetium 99m Sulfur Colloid or Technetium 99m labeled Mebrofenin can be used in the detection and evaluation of masses and metastasis. Which of the following statements correctly describes their properties?

A. Tc99m Sulfur Colloid is rapidly cleared from intravascular space.

B. Tc99m Sulfur Colloid do not contribute to observed background activity.

C. Tc99m Mebrofenin is limited for the detection of gastric bleeding only

D. Both can be visualized in the gastro-intestinal tract but should be cleared from the liver in no more than four hours.

C. Abnormal Perfusion on stress, Thallium 201, normal distribution on relaxation.

Which of the following Myocardial Perfusion patterns suggest that the patient has Myocardial Ischemia?

A. Abnormal resting Tc99m, abnormal stress Tc99m RBC

B. Abnormal resting Thallium 201, abnormal stress Thallium 201

C. Abnormal Perfusion on stress, Thallium 201, normal distribution on relaxation.

D. Normal resting, Thallium 201, abnormal stress Thallium 201

As Thallium 201 is Potassiomimetic, a normal study is one in which the heart calls on the use of Thallium in the same way it calls on the use of Potassium in performing its normal function.

Areas not functioning normally does not call for Potassium, therefore it is a "Cold Spot" on Thallium images.
