We report four patients with unilateral postpartum sacroiliitis presenting with agonising unilateral pain, an elevated ESR, elevated alkaline phosphatase levels, leucocytosis and positive bone scans. The diagnosis of a non-infectious inflammatory cause was supported by the postpartum onset, the response to non-steroidal anti-inflammatory drugs, negative aspiration cultures in two cases and the ...

We describe the case of a 9-day-old female referred for a left posterior mediastinal mass, which we diagnosed as a thoracic neuroblastoma (TNBL) by biopsy. We present this case report to illustrate the classic radiographic, CT, MRI, and nuclear-medicine features of the disease. We believe it is an informative teaching resource for trainees and radiologists. TNBL is a solid childhood tumor of ne...

The authors of this work present two patients, diagnosed with lymphoma and prostate cancer, referred to nuclear medicine department for a gallium-67 scan and a bone scan, respectively. The abnormal accumulation of the radioactivity gave rise suspicion for possible other pathologies. Successive computed tomographic imaging revealed that the patients had had Chilaiditi's syndrome. The authors pre...

This article describes a 28-yr-old black man with sickle cell anemia who presented with severe chest pain secondary to acute infarction of the body of the sternum, hypoventilation, and hypoxemia with no evidence of acute chest syndrome. A bone scan performed 5 days after admission revealed increased uptake in the sternum, suggesting sternal infarction. Repeat bone scan performed 2 mo later demo...

BACKGROUND This study presents an alternative in reconstruction, using free skin flaps in combination with pedicled mandible bone flaps for complex lateral mandibular defects. METHODS In all, 13 patients were included in this prospective study. Pedicled mandible myo-osseous flaps were used for reconstruction of bone defects of the lateral mandible in combination with free skin flaps, includin...

Ionizing radiation has many practical applications, but it is also, as it is well known, dangerous to human health. The purpose of this study was to estimate the dose and exposure for medical staff involved in sentinel node assay and to determine how safe this assay really is. The theoretical method was used for calculation. Three groups of medical staff were selected: nuclear medicine speciali...

OBJECTIVE Pathology of the external and middle ear is the most frequent reason to prescribe antibiotics and perform surgery in children and young adults. In the majority of cases imaging studies are not performed; the need for imaging comes when complications are suspected or when treatment is not effective. This paper discusses indications for temporal bone imaging studies and presents the mos...

ReSultS: The study included 228 patients. Lymphedema was diagnosed clinically in 170 subjects and confirmed by lymphoscintigraphy in 162 (117 primary lymphedema, 45 secondary); 58 patients were thought to have a condition other than lymphedema and all had negative lymphoscintigrams (95% sensitivity, 100% specificity). A subgroup analysis of the 8 patients with clinical lymphedema but negative l...

OBJECTIVE To evaluate the performance of published guidelines compared with that of current practice for radiographic staging of men with newly diagnosed prostate cancer. MATERIALS AND METHODS Using data from the Michigan Urological Surgery Improvement Collaborative clinical registry, we identified 1509 men diagnosed with prostate cancer from March 2012 through June 2013. Clinical data includ...

Dynamic bone scanning with (99m)Tc-labeled diphosphonates and (18)F-labeled sodium fluoride provides functional information sensitive for subtle changes in bone turnover and perfusion, which assists the clinical management of numerous osseous pathologies. This article reviews the mechanisms of uptake of (99m)Tc-labeled diphosphonates and (18)F-sodium fluoride and discusses and compares the perf...
