[18F]KF, considered as a reference standard for positron emission tomography of the skeletal system, was produced by the bombardment of enriched water ([18O]H2O>95%) with high energy protons in NRCAM cyclotron. After the extraction of fluoride from enriched water as KF, and passing it through microbial filter and fine adjustment of acidity and osmolality, it was converted into an injectab...

Eosinophilic granuloma is benign end of the spectrum of the Langerhans cell histiocytosis (LCH) which is characterized by solitary or multiple lesions in bones, skin, lung, lymph node etc. Here, we present a case of a 13-year old boy with pain and swelling in the right parietal region of skull with no other complaint. A computerized tomography (CT) scan and subsequent fine needle aspiration cyt...

Mediastinal epidermoid cyst is a rare condition that is considered as a congenital disorder. Various manifestations from asymptomatic cases to serious symptoms may be found in these patients. However, some cases may be diagnosed incidentally. Here, we report an old man with recurrent pneumonia who demonstrated symptoms of respiratory distress and chest pain. The high resolution computed tomogra...

conclusions pet/ct can provide diagnosis and more accurate staging, location of tumor with its capability in providing the anatomical and physiological information synchronizes. therefore pet/ct plays an important role in oncology. objectives in this paper, we evaluate application of pet/ct for improve oncologic imaging. methods the papers were searched in pubmed and scopus databases with the r...

Emerging materials and methods in biomedical imaging and biophotonics are improving patient outcomes. More specifi cally, the utilization of biomedical diagnostics and therapeutic advances in methods such as magnetic resonance imaging (MRI), computed tomography (CT) imaging, photoacoustic tomography, photothermal optical coherence tomography, and targeted photothermal therapy (PTT) have been sh...

Introduction: Accurate evaluation of femoral and tibial torsion is essential for children or adult with legs deformity, becuse incorrect legs morphogenesis can lead to pathological situation. CT scan is commonly used for the measurement of skeletal bone parameters. But, disability in imaging from standing and sitting posture and absorb dose of patients are deficits of this meth...

A review of state-of-the-art maxillofacial imaging is presented. Current imaging techniques include intra-oral radiographs, dental panoramic tomography, multidetector helical computed tomography, cone-beam computed tomography (CBCT) and magnetic resonance imaging (MRI). The commonest conditions encountered in clinical radiological practice are reviewed, including maxillofacial deformities, comp...

Accurate diagnosis of tumors needs much detailed information. However, available single imaging modality cannot provide complete or comprehensive data. Nanomedicine is the application of nanotechnology to medicine, and multimodality imaging based on nanoparticles has been receiving extensive attention. This new hybrid imaging technology could provide complementary information from different ima...

Correct identification of metastatic sites in recurrent prostate cancer (PCa) is of crucial importance because it leads to further treatment decisions. To provide an overview on current imaging procedures and their performance in recurrent PCa. Medline search via PubMed was performed with the keywords imaging, recurrent, and prostate cancer as well as more detailed searches including the keywor...
