Magnetic resonance imaging (MRI) is a technique that produces cross-sectional images of a patient's body, using magnetism and radio waves.1 Here we discuss advantages and disadvantages of MRI scans and practical issues for clinicians and patients.BMJDrug & Therapeutics Bulletin...
One way to do that is to only biopsy men who have a suspicious lesion on an MRI scan, and only sample the lesion instead of systematically taking pieces from all around the prostate, which is typical. This is the route that University of Gothenburg’s Hugosson tested in the NEJM study....
Respiratory motion can impact the efficacy and safety of radiation therapy in the thorax and abdomen. For treatments using an MRI-guided linac, free-breathing 4D-MRI is a promising alternative to 4D-CT for motion management, providing excellent soft-tissue contrast with no ionizing radiation. High...
directions were encoded, and the total scan time was approximately 2 h. The diffusion tensor and its four quantitative indices, axial diffusivity (AD), radial diffusivity (RD), mean diffusivity (MD), and fractional anisotropy (FA)28were reconstructed from the acquired data by using an in-house...
A single beam destroys pathological tissue as big as a grain of rice. The session continues until the entire neoplasm has been destroyed. After treatment, an ultrasound or MRI scan evaluates the result. After HIFU, the 10-year survival rate for patients with early-stage prostate cancer is betw...
This approach reduces the amount of opening for the TMJ OA patients that often present pain during opening; however, when the patients were asked to open the mouth as much as they could even with pain (i.e., RangeUnaMAx) the values were not statistically significant between the groups. In...
You also should talk to your doctor before having some kinds of imaging tests. With amagnetic resonance imaging(MRI) or computed tomography (CT) scan, doctors sometimes use a dye to help them see a specific area of your body better. In rare cases, this dye can cause serious conditions cal...
Abdominal fat (subcutaneous and visceral) and hepatic fat were assessed by magnetic resonance imaging (MRI) using a multiple‐slice MRI 1.5 T scan (Signa LX Echo Speed Plus Excite, General Electric, Milwaukee, Wisconsin), as described11. Statistical analyses were performed with SPSS 23.0 (IBM, ...

MRI guided cardiac interventional systems are configured to generate dynamic (interactive) visualizations of patient anatomy and medical devices during an MRI-guided procedure and may also include at least one user selectable 3-D volumetric (tissue characterization) map of target anatomy, e.g., a de...
