Numerous injuries and pathologic conditions can involve the hallucal sesamoidal complex and plantar capsular structures of the first metatarsophalangeal joint. Although clinical history and presentation are important in developing a reasonable differential diagnosis, there is often considerable overlap in the clinical presentation and physical findings between various pathologic entities. Imagi...

The postoperative ultrasound pattern in 33 patients with previous surgery for unilocular hydatid disease of the liver was investigated. Each patient was submitted to liver scanning with 99mTc pertecnate, as well as to real time ultrasound examination. The patients were divided into three groups according to the type of surgery performed, namely; omentopexy, introflexion and omentoplexy with int...

introduction: gastric drainage disorder is one of the complications of gastric pull-up and esophagectomy after surgery which might lead to esophageal cancer and benign strictures. the aim of this study was to determine the role of pyloromyotomy on gastric drainage. materials and methods: in this prospective randomized controlled clinical trial study, we studied 51 patients in two matched groups...

The precise localisation of osteoarthritic changes is crucial for selective surgical treatment. Single photon-emission CT-CT (SPECT-CT) combines both morphological and biological information. We hypothesised that SPECT-CT increased the intra- and interobserver reliability to localise increased uptake compared with traditional evaluation of CT and bone scanning together. We evaluated 20 consecut...

Although bone scanning is a test primarily concerned with skeletal abnormalities, important nonosseous findings are occasionally present on the images. To gauge the significance of such nonosseous uptake and, in particular, to determine whether these findings contain useful diagnostic information, the technical and medical staff in nuclear medicine must recognize the various patterns of nonbony...

The purpose of this methods paper is to offer pediatricians and nuclear medicine physicians a diagnostic protocol for performing lymphoscintigraphy in newborns that may be useful for enhancing diagnosis and management of newborns with congenital lymphatic abnormalities. Indications for lymphoscintigraphy, choice of tracer, optimal dose, routes of administration, methods of data acquisition, tim...

We present a case of a 78 year-old woman who was operated for mass of the left posterior chest. Histologically, the excised tumor was consistent with extraskeletal osteosarcoma. She was referred to the nuclear medicine department for a bone scan. The Tc -HDP scintigraphy exhibited multiple focal round areas of increased tracer uptake in soft tissue. This was proved to be multiple metastasis in ...
