A 23 day old infant patient underwent 99mTc-denatured RBC scanning for locating possible ectopic spleen in our department.  The scan showed no tracer activity in normal splenic bed in the left upper quadrant and an ectopic spleen was shown on the right side of abdomen inferior to the liver. 99mTc-denatured RBC scan is an easy and available method for splenic localization i...

In-vitro labeling of RBC with 99mTc is an intricate procedure and there is always a need foran alternate blood pool imaging agent. The aim of this study was to prepare an effective nanosized liposome (NLs) similar to human RBC for blood pool scintigraphy. This study formulatesPEG-NLs and non-PEG-NLs using film method plus high pressure homogenization technique.Biodistribution studies were perfo...

This article reports an interesting case of frank epistaxis presenting as an incidental finding on Tc RBC scintigraphic evaluation of cavernous haemangioma in the liver.

Hemangiomas are rare tumors in the calvarium and represent 2% of osseous calvarial lesions. Dynamic Tc-99m RBC blood pool scintigraphy has a high positive predictive value for cavernous hemangiomas of the liver. This scintigraphic technique can be used for identifying cavernous hemangiomas at other anatomic sites. We present a case in which a tagged RBC blood pool scan was used for further char...

Tc-99m labeled RBC scintigraphy is commonly employed in the evaluation of acute gastrointestinal bleeding. On Tc-99m RBC studies gastrointestinal bleeding is seen as an initial focus of increased radiotracer activity that on subsequent images increases in intensity and changes position in a pattern that conforms to segments of bowel. We report a case of a patient with multiple episodes of hemat...

A 68-year-old male, known case of abdominal aortic dissection and recent aortic stent insertion, presented with gross hematuria. The urologists suspected aoro-ureteric fistula and performed open surgery (ureterolysis). Tc-99m labeled red blood cell (99mTc-RBC) scintigraphy was ordered to confirm the diagnosis and localize the possible aorto-ureteric fisula, Considering sustained gros...
