We have devised a new position (Monzen position) which can suppress the influence of scattered rays from surrounding organs (liver, etc.) when conducting myocardial imaging. Unlike the conventional techniques, which require a waiting period of 30-60 minutes before imaging can be started after the infusion of technetium-99m sestamibi or technetium-99m tetrofosmin, this position allows single-pho...

introduction: this study was done to determine the site of obstruction in lacrimal drainage system in asian patients suffering from epiphora and to determine the transit time taken for the tracer material to reach the lacrimal sac and the nasal cavity. methods:dacryoscintigraphy was performed using radionuclide technetium-99m pertechnetate (99mtc) in 34 patients suffering from unilateral or bil...

Objective: To determine the correlation of 18F-FDG SUV value with bone scintigraphy findings, i.e. uptake Tc-99m in diagnosed cases malignancy sclerotic metastasis.
 Study Design: Prospective longitudinal study.
 Place and Duration Study: Armed Forces Institute Radiology Imaging, Rawalpindi Pakistan, from Sep 2020 to Mar 2021.
 Methodology: This study included 30 patients age 18 ...

Paracoccidioidomycosis (PCM) or South American Blastomycosis is a systemic fungal infection caused by a dimorphic fungus, Paracoccidioides brasiliensis. It represents the most important systemic mycosis in South America and with higher prevalence among male inhabitants of the rural area. PCM usually affects the lungs, and rarely the intestines. The authors report three cases of PCM, treated at ...

This case report illustrates the dynamic and static renal scintigraphic images of a patient with an unusual large diverticulum of the renal pelvis. The initial diagnosis by intravenous pyelography (IVP) and ultrasonographic (US) examination was a renal pelvic diverticulum of the left kidney, and the patient was referred to the nuclear medicine department for exploration of the effect of the pel...

BACKGROUND Acute lower gastrointestinal bleeding (LGIB) is a major cause of morbidity and mortality. Multidetector row computed tomography (CT) with gastrointestinal (GI) bleed protocol is a novel diagnostic technique for detecting and localizing LGIB. Being rapid and noninvasive, it may be useful as a first-line modality to investigate cases of acute LGIB. GOALS To assess and compare diagnos...

UNLABELLED Parathyroid scintigraphy and high-resolution ultrasonography are frequently used as preoperative localization procedures in primary hyperparathyroidism. However, when thyroid disease coexists, their diagnostic accuracy is probably abated. DESIGN 56 patients with primary hyperparathyroidism were prospectively evaluated with parathyroid scintigraphy (with either thallium or technetiu...

Methods Seventeen postoperative neurosurgical patients without pulmonary disease volunteered to participate in the study and were randomly ventilated in PS (n = 8) or VC (n = 9) with constant inspiratory flow. Diethylenetriaminepentaacetic acid labelled with technetium-99 m (2 mCi/3 mL) was administered using a vibrating-mesh nebulizer (Aerogen Solo, Aerogen Ltd., Galway, Ireland) connected to ...
