RATIONALE AND OBJECTIVES Treatment of brain neoplasms can greatly benefit from better delineation of bulk neoplasm boundary and the extent and degree of more subtle neoplastic infiltration. Magnetic resonance imaging (MRI) is the primary imaging modality for evaluation before and after therapy, typically combining conventional sequences with more advanced techniques such as perfusion-weighted i...

OBJECTIVE To describe the multiparametric magnetic resonance imaging (MRI) appearance of prostate tuberculosis. MATERIALS AND METHODS Six patients with prostate tuberculosis were analyzed retrospectively. The mean age of the patients was 60.5 years (range, 48-67 years). The mean prostate specific antigen concentration was 6.62 ng/mL (range, 0.54-14.57 ng/mL). All patients underwent a multipar...

As reported previously, the 61-year-old male Chinese patient suffering from the inflammatory myofibroblastic tumor of the right thigh without bone involvement was performed a surgical excision and a local radiotherapy two years ago. However, a moderately soft and painful 200 × 100 mm mass of the posterior thigh, where magnetic resonance imaging (MRI) scans revealed an inhomogeneously hyperinten...

Purpose: Dynamic contrast-enhanced (DCE)-MRI has a promising role in breast cancer detection and lesion characterisation. Diffusion-weighted imaging (DWI) acts as an adjunct the differentiation between benign malignant lesions. The purpose of study was to evaluate efficacy DCE-MRI DWI differentiating Methods: In prospective conducted March 2019 February 2020, 60 patients with lesions underwent ...

Pseudoangiomatous stromal hyperplasia (PASH) of the breast is a benign myofibroblastic process. We present the case of a 17-year-old girl who underwent diagnostic work-up due to an enlargement of her left breast. She was submitted to ultrasounds and magnetic resonance imaging (MRI) which depicted a 14 cm lesion in her left breast. The patient was later operated and histology revealed PASH. Alth...

D. Wang, G. Cowin, K. McMahon, D. M. Doddrell Centre for Magnetic Resonance, The University of Queensland, Brisbane, Qld, Australia Introduction Gradient coils in magnetic resonance imaging (MRI) play an increasingly important role as many advanced imaging sequences developed in recent years normally require faster and stronger gradients. To meet this demand, gradient designers employed differe...

Adnexal masses are spectrum of diseases from benign non neoplastic and neoplastic masses to malignant neoplasms. Endovaginal ultrasonography (US) is the fisrt and invaluable modality for assessment of adnexal masses because it is available and has a high negative predictive value. Important morphologic features are solid (vascularized) tissue, vascular and thick septations, and papillary projec...

Because of its noninvasive nature and provision of quantitative measures of a wide variety of physiologic parameters, functional magnetic resonance imaging (MRI) shows great potential for research and clinical applications. Over the past decade, application of functional MRI extended beyond detection of cerebral activity, and techniques for abdominal functional MRI evolved. Assessment of renal ...

PURPOSE We aimed to define multiparametric magnetic resonance imaging (MRI) findings to differentiate between pulmonary artery sarcoma (PAS) and pulmonary thromboembolism (PTE). METHODS Eleven patients with suspected PTE were prospectively included to undergo pulmonary MRI before surgery or biopsy. MRI protocol included an unenhanced sequence, diffusion-weighted imaging (DWI, b=800 s/mm2) and...

Marchiafava-Bignami disease (MBD) is a form of toxic demyelinating disease more often seen in chronic alcoholics. The disease process typically involves the corpus callosum and clinically often presents with altered sensorium, neurocognitive defects or seizures with acute cases often deteriorating to comatose state. The death rate is high. We report a rare case of MBD with complete clinical rec...
