A 36-year-old woman with right upper quadrant abdominal pain since three months previously and no other significant medical history was referred for evaluation of an abdominal mass. Upon clinical examination, a large palpable mass in the mid -upper abdominal area was noted. Abdominal ultrasound and spiral CT-scan showed a large hepatic mass in the left liver lobe. The patient was referred for T...

We present a patient with a remote history of splenectomy and recent hemicolectomy for colon adenocarcinoma. On routine surveillance chest/abdomen/pelvis CT, a lesion suspicious for hepatic metastasis was identified. Followup MRI was inconclusive. For more specific tissue characterization, imaging with Tc-99m heat-damaged RBCs was obtained to guide further patient management. Tc-99m-labeled, he...

A 63-year-old woman had gone to the emergency room several times for recurring episodes of headaches, tachycardia with palpitations, anxiety and sweating in the context of hypertensive crisis. High levels of adrenaline, noradrenaline, metanephrine and normetanephrine were found in urine. RM detected a hypervascular 5 cm in size right adrenal mass in contact with the inferior cava vein compatibl...

Background The ability to follow the distribution and migration of biologically active cells in human is essential for the development of cell-based therapies and diagnostics. Nuclear medicine imaging is widely applied in clinic as an attractive technique for in vivo WBC and stem cell tracking. The aim of this study was to evaluate prosthesis infection of a 51 years old man with previous histo...

Introduction: Hemangiomas are the most frequent benign tumors of the liver and detecting them from metastasis or other malignant hepatic tumors is of outmost importance. 99mTc- RBC scan is highly specific and is the method of choice for this differentiation. This scintigraphy is performed in Planar and SPECT modes. These two procedures are in agreement most of the times, however since SPE...

Arteriography to detect gastrointestinal bleeding, which is often intennittent, is only likely to yield diagnostically useful infonnation if the patient is actively bleeding at a rate of greater than 1.0 cclmin at the time of the procedure. To avoid the unnecessary morbidity of a negative arteriogram we studied Tc-99m in vitro labeled red blood cell (RBC) scintigraphy as a screening test for ar...

The objective of this study was to compare the binding of cyclosporine to blood proteins between four healthy subjects and five liver and eight renal transplant patients. Fresh heparinized blood was obtained, to which sufficient quantities of tritium-labelled cyclosporine and unlabelled cyclosporine were added to blood samples or red blood cell (RBC) suspensions. Concentrations of cyclosporine ...
