Thyroid scintigraphy is a method that formed more than 60 years ago and retains its importance for the diagnosis assessment of risk nodular malignancy. The review examines use scintigraphic in functional metabolic goiter. Prerequisites thyroid nodes screening with short-lived 99mTc-pertechnetate are outlined. Information provided on principles preparation pharmacokinetics, as well variants acti...

Meckel's diverticulum (MD) is the most common congenital gastrointestinal anomaly. About 50% of diverticulae contain ectopic gastric mucosa. Gastric mucosal secretions can cause peptic ulceration resulting in pain, bleeding and perforation. Technetium-99m ((99m)Tc) pertechnetate scintigraphy is helpful in diagnosing ectopic gastric mucosa. We have conducted a retrospective analysis of scintigra...

Abstract Purpose Molecular imaging with 99m Tc-methoxy-isobutyl-isonitrile ( Tc-MIBI, MIBI) has been used in the assessment of thyroid nodules (TNs) for more than two decades. Many studies showed that MIBI is a suitable tool to rule-out malignancy when negative. However, relatively low specificity and accuracy have described, thus, limiting its acceptance clinical practice. Additionally, differ...

INTRODUCTION Meckel's diverticulum is a common congenital abnormality of gastrointestinal tract in children. Planar scintigraphy using Technetium-99m pertechnetate is widely used in the diagnosis of Meckel's diverticulum. Single photon emission computed tomography/computed tomography (SPECT/CT) fusion imaging may help to locate the Meckel's diverticulum lesion. We now present a Meckel's diverti...

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...

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...
