Introduction: Radical prostatectomy is an effective curative treatment option for organ-confined prostate cancer. There is a recent trend in offering curative treatment to patients with oligometastatic disease. More sensitive imaging modalities can identify oligometastatic disease that is not usually detected by conventional imaging techniques. Case presentation: We present a case in which a s...

Echo-planar imaging is a fast magnetic resonance (MR) imaging technique that allows acquisition of single images in as little as 20 msec and performance of multiple-image studies in as little as 20 seconds. Echo-planar imaging achieves its speed by obtaining all spatial-encoding information after a single radio-frequency (RF) excitation. Conventional imaging requires multiple-RF excitations, se...

Background and Aims: With the increasing use of CT (Computed Tomoghraphy) scans in dentistry especially in the implantology, there may be significant increases in the radiation exposure and its risk. During the last year’s ConeBeam Computed Tomoghraphy (CBCT) has been introduced as an imaging modality for dentistry. The aim of this review article was to present comprehensive inform...

Background & Aims: Conventional radiography is used for the diagnosis of problems such as dental caries and failure in root canal therapy. The diagnosis accuracy of conventional radiography is acceptable in the evaluation of anatomical and pathological structures. However, it seems that by using digital radiography we can obtain more information in this field. The aim of this study is to compar...

Susceptibility-weighted imaging (SWI) has continued to develop into a powerful clinical tool to visualize venous structures and iron in the brain and to study diverse pathologic conditions. It is a new art which evaluates and exploits the properties of blood, iron and other tissues. It is a magnitude or filtered phase images or combination of both, obtained with high-resolution 3D fully velocit...
