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...

   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. ...

Objective: The development of new radiopharmaceuticals capable specifically imaging cancer is an important research area. For this reason, the aim study to investigate cell binding novel developed nanoradiopharmaceutical ([99mTc]Tc-nab-PTX) on HT-29 line (human colorectal adenocarcinoma cells).
 Material and Method: In study, nab-PTX was labeled with [99mTc]Tc, labeling efficiency in vitro...

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...

Gastrointestinal bleeding is a frequently encountered clinical entity, the incidence of which has remained relatively constant at approximately 70 episodes per 100,000 population per year.1 Although the treatment of gastrointestinal bleeding is often straightforward, the identification and localization of the source of bleeding is more challenging. Due to intermittent nature of bleeding, detect...

We presented a pediatric case with a history of intermittent melena for 3 years because of angiodyplasia of small intestine. The results of frequent upper gastrointestinal endoscopies and colonoscopies as well as both Tc-red blood cell (RBC) and Meckel's scintigraphies for several times were negative in detection of bleeding site. However, Tc-RBC scintigraphy with single-photon emission compute...

OBJECTIVE The aim of this study was to compare the renal function measured with either 99mTc-DTPA or 99mTc-EC dynamic scintigraphies with that measured using 99mTc-DMSA static scintigraphy. METHODS the values of relative renal function measured in 111 renal dynamic scintigraphies performed either with 99mTc-DTPA (55 studies) or with 99mTc-EC (56 studies) were compared with the relative functi...

This study aimed to prepare a novel radiopharmaceutical for the detection of brain disorders at early stages in susceptible patients.Promazine hydrochloride was labeled with 125I by direct electrophilic substitution reaction high labeling yields 92.6 ± 3.24 %. The yield and vitro stability 125I-promazine were determined paper electrophoresis, chromatography (PC) High performance liquid (HPLC). ...
