UNLABELLED Parathyroid cystic adenomas are often misdiagnosed as thyroid cysts and routine preoperative diagnostic tools, such as ultrasonography (US) or 99m technetium-sestamibi (99mTc-MIBI) scans, cannot clearly distinguish between these entities. We present a 67-year-old hypercalcemic woman with a cervical cystic lesion who had negative sestamibi scan results. Her laboratory data indicated p...

The purpose of this study was to validate whether dipyridamole stress ultrasonic tissue characterization with cyclic variation of integrated backscatter (CVIBS) compared with dipyridamole stress echocardiography and dipyridamole stress Tc99m-MIBI SPECT myocardial perfusion scintigraphy could predict myocardial ischemia in patients with chronic coronary artery disease. Twenty patients (16 M, 4 F...

The role of various radionuclide investigations, including parathyroid scintigraphy, bone scintigraphy and serum parathormone estimations in the diagnosis of primary hyperparathyroidism is reviewed briefly. The initial experience with the dual isotope (Tl-201; Tc-99m) subtraction scintigraphy for the preoperative localization of parathyroid adenomas is presented (JPMA 37 : 237, 1987).

Gastrointestinal duplication cysts are a rare congenital malformation in the gastrointestinal tract, most commonly seen ilium. The present study reported child with mid ileal cyst ofthe ectopic gastric mucosa that was diagnosed by Technetium-99m pertechnetate single-photon emission computed tomography-computed tomography (SPECT-CT) scintigraphy. can massive lower bleeding early childhood (Mecke...

To evaluate the value of preoperative ultrasound-guided fine-needle aspiration (UG-FNA) of ultrasound-detected suspicious parathyroid nodules for localization in Tc-99m MIBI-negative primary hyperparathyroidism patients.From May 2008 to December 2016, Tc-99m MIBI-negative primary hyperparathyroidism patients with ultrasound-detected suspicious cervical nodules underwent UG-FNA. The sample obtai...

Right ventricular apical pacing (RVAP) with a left bundle branch block on the electrocardiogram may result in regional wall motion abnormalities and decreased left ventricular function (LVF). Furthermore, perfusion defects in dipyridamole technetium-99m-methoxisobutylisonitrile ((99m)Tc-MIBI) myocardial perfusion imaging may occur despite a normal coronary angiogram. In a 68 years old patient, ...

INTRODUCTION The diagnostic efficacy of somatostatin receptor scintigraphy labeling with 111 indium in the localization of tumors has been assessed in a limited number of patients with contradictory outcomes. Here, we describe the case of a patient with an ectopic adrenocorticotropic hormone-producing bronchial carcinoid tumor diagnosed preoperatively using technetium-99m-labeled octreotide ace...

UNLABELLED New imaging techniques have been introduced to assess the extent and severity of disease in multiple myeloma (MM) patients. The aim of our study was to compare newer imaging modalities-such as (18)F-FDG PET/CT, (99m)Tc-methoxyisobutylisonitrile ((99m)Tc-MIBI) scintigraphy, and MRI-to assess their relative contribution in the evaluation of MM patients at diagnosis. METHODS Thirty-th...
