Objective: A commercially available dual energy X-ray absorptiometry scanner normally provides more than 1 scan mode. The differences between scan modes affect scan time, received radiation dose, and quality of the scan image. A phantom study was performed to evaluate the performance of different scan modes for anteriorposterior spine scan. Patients and Methods: To measure the entrance skin exp...

a 29- year old female with bone pain and history of precocious puberty was referred for bone scintigraphy. on physical examination café au lait macular spots were noted on her neck, buttocks and left leg. bone scan showed multiple areas of intense increased activity which was in favour of polyostotic fibrous dysplasia. considering the presence of polyostotic fibrous dysplasia, precocious pubert...

BACKGROUND Controversy persists as to the need for both MIBG and bone scanning in routine evaluation of neuroblastoma. AIM To compare the efficacy of I-131- metaiodobenzylguanidine (MIBG) scan against that of conventional Tc99m- methylene diphosphonate (MDP) bone scan for the detection of skeletal deposition of neuroblastoma. METHODS AND MATERIAL The study included 57 patients (36 boys, 21 ...

BACKGROUND Bone infection is a common issue in infectiology. The gold standard for evaluating bone infection is the white blood cell (WBC) scan. In our practice the WBC scan is coupled with a bone scan. Discordances in the results of these two examinations are a common occurrence in daily practice. We decided to investigate the meaning of these discordances. MATERIALS AND METHODS Two hundred ...

An enostosis or bone island is a benign bony lesion that is almost diagnosed based on clinical and radiologic defining characteristics. One of the known diagnostic procedures in the evaluation of enostosis is bone scintigraphy. Generally, we don’t expect to see increased uptake by enostosis in the bone scan. Herein we present a 52-year-old lady who was suffering from chronic low back pain that ...

Background: The aim of this study to assess the role of 99mTc-HMPAO leucocyte scintigraphy combined with 99mTcMDP bone scintigraphy in the diagnosis of the diabetic foot infection. Methods: 50 diabetic patients with suspected osteomyelitis were included. The HMPAO-Leucocytes/MDP scan was considered to be consistent with osteomyelitis when the HMPAOLeucocytes uptake was concordant with MDP bone ...

introduction: ubiquicidin (ubi) 29-41 is a synthetic antimicrobial peptide that binds with the microbial cell membrane at the location of infection. this study was conducted to evaluate its probable efficacy as an infection-imaging agent with potential to differentiate bacterial infection from sterile inflammation in humans. methods: fifteen diabetic foot patients (10 males and 5 females) with...
