Mri Characterization Of Sellar & Parasellar Lesions And Their Clinical Correlation

Aims & Objectives: This study aimed to describe the prevalence of the various lesions and to characterize imaging features of the sellar and parasellar lesions and to correlate between clinical and radiological diagnosis. Methodology: This study was done for the characterization of sellar & parasellar lesions with the help of MRI scan, which were done at the MRI centre, MB Hospital, Udaipur, Rajasthan from January 1, 2017, to December 2017. Medical case papers were reviewed for the primary clinical indication that led to a referral for pituitary MRI and serum prolactin levels were noted to follow up regarding surgical or conservative management was done. After analyzing the data results were expressed as frequency of occurrence and percentages of various lesions which were compared with clinical findings. Results: The study population consisted of 80 patients, of which majority were females. MRI revealed abnormality in 68% cases and it was found that combined sellar and suprasellar involvement was there in most of the patients, followed by pure intrasellar and parasellar involvement. Conclusion: The sellar and parasellar regions can be affected by a wide variety of lesions with almost similar presentation. When symptoms of mass effect, visual field deficits and endocrine abnormalities are not sufficient to distinguish these lesions, the use of MRI can helpful in reaching the proper diagnosis

Background: Diffusion weighted MRI imaging is a new technique which measures the microscopic motion of water protons. It provides image contrast that is dependent on the motion of water molecules, which may be substantially altered by disease. Methodology: In our prospective study a total of 80 cases of various intracranial pathologies were evaluated.MR imaging including T1, T2, fluid attenuation inversion recovery (FLAIR), gradient sequences, ADC and diffusion weighted imaging were obtained in various planes. Aims & Objectives: To assess the role & efficacy of Diffusion-weighted imaging in evaluation of intracranial pathologies. To assess the role & efficacy of Diffusion-weighted imaging in evaluation of early infarcts & differentiating early infarcts from chronic infarcts. To assess the role of Diffusion-Weighted MR Imaging for differentiating Rim-Enhancing Brain lesions. Results: Infract was the most Common lesions detected in our study. DW MRI is highly sensitive in detection of hyperacute and acute infract as compared to conventional MR (T2 & FLAIR). Other detected lesions include Meningioma, Abscess, Encephalitis, Acute Hematoma, ADEM, Medulloblastoma & Subdural Empyema
