Background and Purpose. In pyogenic brain abscess, hemorrhage in the walls is considered exceptional. Recently, hemorrhagic changes in the walls of pyogenic abscess have been demonstrated on susceptibility weighted imaging with 3T MRI. Here, we report hemorrhagic changes in the walls of pyogenic brain abscess on susceptibility weighted imaging with 1.5T MRI. Method. MRI of brain was done using ...
BACKGROUND Hepatic cirrhosis is a common pathway of progressive liver destruction from multiple causes. Iron uptake can occur within the hepatic parenchyma or within the various nodules that form in a cirrhotic liver, termed siderotic nodules. Siderotic nodule formation has been shown to correlate with inflammatory activity, and while the relationship between siderotic nodule formation and mali...
ObjectiveTo determine whether susceptibility map-weighted imaging (SMWI) was superior to conventional susceptibility-weighted (SWI) in the diagnosis of Parkinson’s disease (PD) and its correlation with 123I-2bcarbomethoxy-3b-(4-iodophenyl)-N-(3-fluoropropyl)-nortropane single photon emission computerized tomography (123I-FP-CIT SPECT).MethodsBetween May 2017 February 2018, 125 consecutive patie...
BACKGROUND AND PURPOSE MRI has been increasingly used in the evaluation of acute stroke patients. However, MRI must be able to detect early hemorrhage to be the only imaging screen used before treatment such as thrombolysis. Susceptibility-weighted imaging, an echo-planar T2* sequence, can show intracerebral hemorrhage (ICH) in patients imaged between 2.5 and 5 hours from symptom onset. It is u...
BACKGROUND Glioma is the most common and most difficult to treat brain cancer. Despite many efforts treatment, efficacy remains low. As neurosurgical removal is the standard procedure for glioma, a method, allowing for both early detection and exact determination of the location, size and extent of the tumor, could improve a patient's positive response to therapy. NEW METHOD We propose applic...
زمینه و هدف: سرطان پروستات سومین علت مرگ و شایع ترین علت سرطان در مردان مسن است. با توجه به توانایی تشخیصی پایین روش های غربالگری در تشخیص و لوکالیزه کردن تومور، روش های تصویربرداری از جمله magnetic resonance imaging (mri) و diffusion weighted imaging (dwi) در سال های اخیر مورد توجه و استقبال قرار گرفته است. در این تحقیق، ارزش استفاده از dwi برای تشخیص سرطان های پروستات بررسی گردید.روش بررسی: ا...
