Parathyroid scintigraphy
The purpose of this study is not only to describe scintigraphy in parathyroid imaging and the results obtained but also to discuss the merits and limitations of the technique so that its role in today's climate of cost containment, may better be defined.

Planar visual fusion scintigraphy
Planar scintigraphy, while providing useful information about the distribution of the radiopharmaceutical being used, often does not provide adequate information about the surrounding anatomical structures. A proposed method to solve this problem is by registering and fusing a scintigraphic image …

Aspects of paediatric gastro oesophageal scintigraphy
This work is concerned with the application of scintigraphy in studies of foregut motility in paediatric patients; notably oesophageal transit during swallowing, gastro oesophageal reflux (GOR) and stomach emptying as measured by the gastric contents 30 and 120 minutes after deglutition of liquid. …

Tomographic ventilation-perfusion lung scintigraphy in cardiopulmonary disease
… and perfusion can be imaged with lung scintigraphy. Lung scintigraphy is primarily used to diagnose PE. The introduction of 3-dimensional tomographic lung scintigraphy (V/P SPECT) has resulted in an improved accuracy in the diagnosis of PE. Follow-up with V/P SPECT may lead to better …

Optimizing PSMA scintigraphy for resource limited settings – a retrospective comparative study
Methods: The scans of 95 patients with histologically proven PCa who underwent PS with full-body planar and multi-FOV SPECT/CT were reviewed. The detection rates for uptake in the prostate gland/bed and in metastases were compared on planar, SPECT, and SPECT/CT. The agreement between modalities was …

Detection of Symptomatic Heterotopic Gastric Mucosa of the Upper Esophagus using Tc-99m Pertechnetate Scintigraphy
… the Upper Esophagus using Tc-99m Pertechnetate Scintigraphy Heterotopic gastric mucosa of the upper esophagus (HGMUE) often referred to as an inlet patch, is an asymptomatic benign lesion. However, this inlet patch may cause esophageal ulceration and stricture, leading to symptoms such as …

Usefulness of Quantitative Measurement of Three Phase Bone Scintigraphy in Complex Regional Pain Syndrome Type Ⅰ after a Stroke
"뇌졸중 후 제 1형 복합국소동통증후군으로 진단된 환자의 삼상골스캔의 정량적 분석이 임상증상의 정도, 치료반응 및 증상경과와 어떠한 연관성이 있는지 알아보고자 하였다. 연구 대상은 뇌졸중 후 뚜렷한 임상증상과 삼상골스캔에 의해 제 1형 복합국소동통증후군으로 확진된 43명이었다. 삼상골스캔의 정량적 분석을 위하여 방사성동위원소 섭취량을 건측에 대한 환측의 섭취비를 구하였으며, 이러한 정량적 섭취비가 Kozin의 진단 분류 및 치료에 대한 반응, 증상경과와 연관성이 있는지를 분석하였다. 삼상골스캔의 각 영상에서 부위별로 …

골경화성 골전이를 동반한 유방암 환자에서 F-18 fluoride PET/CT의 유용성
… of breast cancer patients. Whole body bone scintigraphy can be used to evaluated bone metastases and also F-18 FDG PET/CT seems to exhibit high specificity and accuracy to detect skeletal metastases. However there is the limitation of F-18 FDG PET in assessing sclerotic bone metastasis …

Significance of Salivary Gland Radioiodine Retention on Post-ablation 131I Scintigraphy as a Predictor of Salivary Gland Dysfunction in Patients with Differentiated Thyroid Carcinoma
PURPOSE: We investigated whether 131Iwhole-body scintigraphy could predict functional changes in salivary glands after radioiodine therapy. METHODS: We evaluated 90 patients who received initial high-dose (≥3.7 GBq) radioiodine therapy after totalthyroidectomy.Allpatients underwent diagnostic (DWS) …

Evaluation of Thyroid to Background Ratios in Hyperthyroid Cats
… the dose based on the severity of disease. Scintigraphy is the best method to quantify the severity of the disease. Previously established scintigraphic quantitative methods, thyroid to salivary ratio (T:S ratio) and % dose uptake, are the most widely recognized measurements. Recently, the …

The use of scintigraphy to study gastric emptying, motility and small intestinal transit in patients who have ingested a selection of common poisons
Poisoning is common and carries considerable morbidity and mortality. Two to three patients are admitted to the Emergency Unit at Groote Schuur Hospital every day with drug overdose. As absorption occurs in the small intestine the rates at which ingested poisons pass into and through the small …

The diagnostic accuracy to Technetium 99m labelled erythrocyte scintigraphy in the investigation of hepatic mass lesions : special reference to hepatic cavernous haemangioma and hepatocellular carcinoma
… have suggested that ⁹⁹ᵐTc erythrocyte blood pool scintigraphy is both highly sensitive and specific for haemangiomas, a basic flaw in all previous studies has been the small number of control patients studied. Bayesian analysis clearly shows that specificity for a test is dependant on the pre-test …

The conclusions drawn from ventilation/perfusion single photon emission computed tomography (SPECT) compared to lung perfusion SPECT and a chest x-ray (CXR) in patients with suspected pulmonary pulmonary thromboembolism
… from studies on whether the ventilation (V) scintigraphy can be safely omitted or replaced by a chest x-ray. These studies were based on planar ventilation perfusion (V/Q) scintigraphy. We evaluated the value of the V single photon emission computed tomography (SPECT) on the final conclusion …
