Evaluation of the accuracy of dynamic contrast enhanced MRI in the diagnosis of invasive prostate neoplasm using pathological findings

Background: Prostate cancer is the most common malignancy in men and the second leading cause of death in all countries of the world. The exact mechanism of prostate cancer is not known. On the other hand, early detection of prostate cancer can lead to a complete cure. Several clinical experiments including Digital Rectum Examination (DRE), biochemistry such as Prostate Specific Antigen (PSA), ...

Standardization of Radiological Evaluation of Dynamic Contrast Enhanced MRI

Dynamic contrast enhanced MRI is applied as an adjuvant tool for breast cancer detection, diagnosis, and follow-up of therapy. Despite improvements through the years in achieving higher spatial and temporal resolution, it still suffers from lack of scanning and processing standardization, and consequently, high variability in the radiological evaluation, particularly differentiating malignant f...

Clinical reasoning: cerebral cavernous malformations.

Lama M. Chahine, MD Michel J. Berg, MD SECTION 1 A 40-year-old man presented for management of seizures. His first seizure was 5 years earlier. Evaluation at that time revealed a hemorrhagic lesion near the occipital horn of the left lateral ventricle. Incomplete surgical excision was performed with indeterminate pathology suggestive of an astrocytoma. MRI demonstrated 7 separate lesions consis...

The cerebral cavernous malformations proteins.

Inherited mutations in three genes lead to the familial form of Cerebral Cavernous Malformations (CCM). These vascular dysplasias most commonly occur in the brain, and manifest as dilated, mulberry-shaped lesions with a single endothelial layer. The consequences of these lesions can be leakage and sequelae such as focal neurological deficits, epilepsy, or hemorrhagic stroke. Until recently, how...
