Three cases of imaging with 99mTc-pertechnetate (99mTcO4) and unusual positive lymph node uptake in the neck are reported hereby. Two cases were later diagnosed to be well-differentiated thyroid carcinoma, (DTC) with nodal metastasis. The third was a confirmed case of carcinoma thyroid that had presented with mass in the neck soon after surgery, being prepared for ablative dose of radioactive i...

Alimentary tract duplications are uncommon congenital anomalies. Although most are symptomatic by the age of 2 years, some remain asymptomatic until adulthood. In one third of all cases, heterotopic gastric mucosa lines the wall of dupli­ cation, and may cause peptic ulceration, gastrointestinal bleed­ ing, fistulization or perforation. We report in this paper, a case of jejunoileal duplication...

Multiple myeloma (MM) is a clonal B-lymphocyte neoplasm of terminally differentiated plasma cells. Imaging modalities which allow the recognition of the effects of myeloma cells on the skeletal system have been utilized for a long time. Herein, we represent a patient with generalized osteoporosis and hypercalcemia, who was referred for parathyroid scan, in whom the widespread bone marrow techne...

Meckel diverticulum is the most prevalent congenital abnormality of the gastrointestinal tract in children. The aim of this study was to review and analyze clinical data on the diagnosis and management of Meckel diverticulum in pediatric patients. The records of 102 pediatric patients (<14 years old) who underwent surgery for Meckel diverticulum at our institute between 2001 and 2015 were revie...

INTRODUCTION Variceal haemorrhage is a potentially life-threatening complication in cirrhotic patients. Identification of patients at high risk for bleeding is particularly important. The aim of this study was to determine the clinical usefulness of per-rectal portal scintigraphy (PPS) in the evaluation of the severity of portal hypertension in cirrhotic patients, in terms of correlation betwee...

OBJECTIVE To investigate in vivo and in humans the mechanisms and kinetics of vagina-to-uterus distribution. DESIGN Controlled clinical study. SETTING Volunteers in an academic research environment. PATIENT(S) Six postmenopausal women undergoing transabdominal hysterectomy were selected. INTERVENTION(S) Women received 0.2 mL of (99m)Tc-pertechnetate vaginally. In three patients the cerv...

Objective. To compare the use of radiolabelled human monoclonal anti-TNF-a scintigraphy with clinical examination and MRI of hands and wrists joints in patients with active RA. Methods. Eight patients with active RA, 28-joint DAS (DAS-28)53.2 and a healthy volunteer underwent whole body and hand/wrist scintigraphy after the administration of anti-human TNF-a labelled with technetium-99m (Tc). O...

This study aims to investigate the radioprotective effects of dimethyl sulfoxide in acute phase radiation-induced lung injury by technetium-99m-diethylenetriaminepentaacetic acid transalveolar clearance scintigraphy a rabbit model. Twenty white New Zealand rabbits were grouped as (1) control, (2) sham irradiation, (3) irradiation plus sulfoxide, and (4) alone. Right hemithorax regions groups ir...
