BACKGROUND The purpose of using a whole-body scanning after the radioactive I-131 treatment is to screen functional residual or metastatic thyroid tissues. In whole-body scanning of some patients, false positive radioiodine I-131 uptakes may be seen in physiological uptake regions or atypical localizations. CASE REPORT A 54 year-old woman underwent total thyroidectomy for papillary thyroid ca...

Dual Energy X-ray Absorptiometry (DXA) is effective in measuring bone mineral density (BMD) in mice for early detection of osteoporosis. However, scanners designed for use with small animals (i.e. PIXImus) are very expensive. Used human DXA machines are cheaper to obtain, but analysis of scans from these instruments is operator-dependent. Obtaining reliable data depends on having a single opera...

Abstract Prostate cancer is one of the most common cancers affecting men. Bone scan part staging modality commonly used to evaluate bone metastasis. A with diffused increased skeletal tracer uptake relative soft tissue, combined faint renal activity known as a superscan. However, primary concern are false negatives associated scans, where diffuse metastasis indistinguishable on superscans. In t...

various dimensions of the human vestibular aqueduct were evaluated in two groups, patient and control, and these measurements were compared. both groups were examined clinically, followed by audiometric evaluation and temporal bone high resolution ct scan. it was found that in approximately one third of the patient group (with idiopathic snhl), the vestibular aqueduct was 1.5 mm or larger. also...

a 21 years old woman presented with a history of sle and skin lesions on the arms, trunk, and abdomen. the left gluteal region was ulcerated and painful and occasionally extruded a chalky white material. the patient referred from rheumatology department for osteomyelitis assessment. on physical examination the patient had hard, nontender lesions on the proximal arms, lower abdomen and lower bac...

Introduction Chronic recurrent multifocal osteomyelitis (CRMO) is an autoinflammatory bone disorder of unknown etiology with a wide range of clinical manifestations. Since CRMO is a systemic disorder that can affect multiple skeletal sites, whole-body imaging techniques (whole body bone scintigraphy -WBBSor whole body magnetic risonance -WBMRI-) provide major contribution to the initial diagnos...

This is a case of follicular thyroid carcinoma with extensive lung, bone and brain metastases. Multi-modality treatments including total thyroidectomy, modified radical neck dissection, cranial radiotherapy and Iodine-131 (RAI) therapy were instituted. Post RAI therapy planar whole body scan showed RAI avid metastases in the skull, cervical spine, bilateral lungs and abdomen. With the use of SP...

A 48-year-old HIV-positive woman presented with progressive pain and stiffness of both shoulders and hips. She was given the diagnosis of polymyalgia rheumatica (PMR) due to high erythrocyte sedimentation rate. However, a 1-week course of prednisolone failed to improve her symptoms. She later discovered a breast lump of which histopathological tissue was consistent with a diffuse large B-cell l...
