A 75-year-old woman presented to our department for a stress myocardial perfusion imaging study with Tc99m-sestamibi. Incidental focal uptake, found in the left upper anterior chest, was initially felt to be located in the left breast. After additional single-photon CT imaging was performed the same day, extracardiac foci within the ribs, spine, and left lung (worrisome for active metastases) w...

BACKGROUND Non-invasive cardiological methods have been used for the identification of myocardial damage in Chagas disease. OBJECTIVE To verify whether the rest/stress myocardial perfusion scintigraphy is able to identify early myocardial damage in the indeterminate form of Chagas disease. METHODS Eighteen patients with the indeterminate form of Chagas Disease and the same number of normal ...

Background: Diagnosis of coronary artery disease (CAD) in patients with left bundle branch block (LBBB) is considered as a challenge in cardiology due to the low accuracy of noninvasive methods such as basal and stress electrocardiography (ECG). This diagnostic challenge can be reduced but not eliminated using dipyridamole as a stress method instead of exercise. The aim of this study was to ass...

BACKGROUND The manifestation of primary hyperparathyroidism with acute pancreatitis is a rare event. Ectopic paraesophageal parathyroid adenomas account for about 5%-10% of primary hyperparathyroidism and surgical resection results in cure of the disease. CASE PRESENTATION A 71-year-old woman was presented with acute pancreatitis and hypercalcaemia. During the investigation of hypercalcemia, ...

Introduction: Mediastinal parathyroid adenoma localization is a rare entity. We report a case of excision by manubriotomy of intrathymic parathyroid adenoma detected by Computed Tomography scan of the chest and neck and confirmed by Technetium-99 m-sestamibi scan (99 mTc-MIBI). Case Presentation: A 68 years old woman with history of hypercalcaemia, PTH elevation and operation for pathological f...

Background. Serial myocardial perfusion imaging with "'Tc-sestamibi (MIBI) was used to evaluate infarct risk area and salvage after thrombolysis. The purpose of this investigation was to determine whether changes in MIBI defect size observed after reperfusion may result in part from distortion of regional and global left ventricular geometry. Methods and Results. Twenty-five open-chest dogs wer...

Myocardial perfusion SPECT imaging with Tc99m-sestamibi is the most accurate non-invasive means of detecting coronary artery disease and assessing the severity of perfusion abnormalities in the patients with coronary stenosis. Though simple and straight forward the results produced by the technique is very much affected by the details being used. One of the main problems with the test, wh...

introduction: radio-guided parathyroid surgery along with other minimally invasive surgeries constitutes the main surgical treatment procedures for different kinds of hyperparathyroidism.  in this article we have reported our experience of radio-guided parathyroid surgery using tc-99m sestamibi. methods: ten patients with hyperparathyroidism included in our study. twenty mci of tc-99m sestamibi...
