UNLABELLED The aim of this study was to investigate joint scintigraphy in rabbits with 99mTc-N-[3-(triethylammonio)propyl]-15ane-N5 (NTP 15-5), a new radiopharmaceutical that specifically localizes in cartilaginous tissues. METHODS Scans obtained after intravenous injection of the 99mTc-labeled compound in normal and arthropathy-induced rabbits were compared with those of the bone-imaging age...

introduction: in this study the automatic separation of oral and salivary gland activity and spontaneous secretion by means of factor analysis for quantitative salivary gland scintigraphy is introduced. methods: after intravenous administration of 99mtc sodium pertechnetate, dynamic scintigraphy was performed. 20 minutes after tracer application 2 ml of lemon juice was delivered to stimulate t...

To determine whether real-time two-dimensional echocardiography (2-D echo) can estimate the extent of myocardial involvement in patients with acute myocardial infarction (MI), regional wall motion on serial short-axis 2-D echo recordings was analyzed and the summed scores were compared with estimates of infarct involvement by thallium-201 reperfusion (Tl) and technetium-99m stannous pyrophospha...

Objective To evaluate SPECT/CT with radiolabeled somatostatin analogues (RSAs) in systemic granulomatous infections in comparison with gallium-67 (67Ga) citrate scintigraphy. Materials and Methods We studied 28 patients with active systemic granulomatous infections, including tuberculosis, paracoccidioidomycosis, pneumocystosis, cryptococcosis, aspergillosis, leishmaniasis, infectious vasculi...

We report a case of esophageal carcinoma that showed extraosseous accumulation of 99mTc-MDP in lymph node metastases to the cervical and paracardial lymph nodes. There are few cases showing abnormal extraosseous accumulation of 99mTc-MDP in esophageal cancer lesion. The patient was a 53-year-old man with advanced esophageal cancer. Bone scintigraphy demonstrated extraosseous accumulations in le...

A 26-year-old male patient who had an 8 years history of recurrent peripheral edema with diarrhea and hypoproteinemia was evaluated. Endoscopic jejunal and ileal biopsy revealed markedly dilated mucosal lymph vessels with no evidence of inflammation. 99mTc-labeled human serum albumin (HSA) scintigraphy showed significant activity accumulating in the gastrointestinal tract to represent 99mTc-HSA...

PURPOSE The purpose of this study was to evaluate the efficacy of retroperitoneal laparoscopic ureterolithotomy for the management of large proximal ureteric stones and the impact of this treatment on postoperative renal function. METHODS The data of 12 patients (7 men and 5 women; mean age, 68.5 ± 8.9 years) with large pyeloureteral junction (2 cases) and upper ureteral (10 cases) stones (25...

Cranial osteomyelitis is a potentially fatal lesion. White blood cell scanning (WBC) with 99mTc-hexamethylpropylene amine oxime (HMPAO) has proven highly sensitive and specific in the diagnosis and follow-up of patients with suspected osteomyelitis. In this report we show the usefulness of SPECT and transmission CT performed simultaneously using a hybrid imaging device for the functional anatom...

OBJECTIVES The aim of the study was to clarify the clinical significance of single-photon emission computed tomography/computed tomography (SPECT/CT) imaging in terms of technetium-99m galactosyl human serum albumin (99mTc-GSA) scintigraphy. To this end, we examined the relationship using data from surgical records of 67 patients with hepatocellular carcinoma who underwent hepatectomy. MATERI...
