Comparison between subtraction and dynamic MRI in assessing treatment response following radiofrequency ablation in patients with hepatocellular carcinoma

The Egyptian Journal of Radiology and Nuclear Medicine, 2021
Background Hepatocellular carcinoma (HCC) is one of the most prevalent cancers worldwide, and if left untreated, one of the most lethal. Ablative therapies including radiofrequency ablation (RFA) play increasingly important role for patients with liver ...

Role of Dynamic Contrast Enhanced MRI in the Evaluation and Characterisation of Breast Lesions with Pathological Correlation [PDF]

Journal of Clinical and Diagnostic Research, 2020
Introduction: Magnetic Resonance Imaging (MRI) has an excellent soft tissue resolution and can detect and accurately characterise lesions which are not seen on other imaging modalities like mammography or ultrasonography.

Imaging of Cerebral Venous Thrombosis

Life, 2022
Cerebral venous thrombosis is a rare cause of stroke. Imaging is essential for diagnosis. Although digital subtraction angiography is still considered by many to be the gold standard, it no longer plays a significant role in the diagnosis of cerebral ...
