mercury is among the most toxic nonradioactive elements which may cause toxicity even at low doses. some studies showed release of mercury from dental amalgam fillings in individuals who used mobile phone. this study was conducted to assess the effect of high-field mri on mercury release from dental amalgam filling. we studied two groups of students with identical tooth decays requiring a simil...

BACKGROUND Prostate cancer is the most common form of cancer and the second leading cause of cancer death in North America. Auto-detection of prostate cancer can play a major role in early detection of prostate cancer, which has a significant impact on patient survival rates. While multi-parametric magnetic resonance imaging (MP-MRI) has shown promise in diagnosis of prostate cancer, the existi...

BACKGROUND Cerebral small vessel disease is a common cause of vascular dementia. Both discrete lacunar infarcts and more diffuse ischaemic changes, seen as confluent high signal (leukoaraiosis) on T2 weighted magnetic resonance imaging (MRI), occur. However, there is a weak correlation between T2 lesion load and cognitive impairment. Diffusion tensor MRI (DTI) is a new technique that may provid...

conclusion the study data highlighted good value of iodine-based material decomposition images of spectral ct in assessment of both lipiodol deposition and residual cancer for follow-up of hcc patients previously treated with tace. background it is critical to follow up hepatocellular carcinoma (hcc) after transcatheter arterial chemoembolization (tace) in clinical practice. computed tomography...

osteomyelitis in childhood can be a challenging diagnosis. imaging plays an important role in the diagnosis of osteomyelitis in children, and the imaging findings are crucial in the treatment decision. pediatric hematogenous osteomyelitis may have variable radiological expression, which is influenced by the age and condition of the patient, the virulence of the causative agent, the stage of the...

The aim of this study was to investigate the value of T(2) (*)-weighted gradient echo imaging (GRE T(2) (*)-WI) for the detection of familial cerebral cavernous malformation (FCCM). Twenty-six members of 2 families with FCCM were examined using computed tomography (CT), conventional magnetic resonance imaging (MRI) and GRE T(2) (*)-WI sequences. We identified 12 cases of FCCM using GRE T(2) (*)...
