Title: Unveiling the Integral Role of Magnetic Resonance Imaging in the Comprehensive Evaluation and Diagnosis of Spinal Dysraphism Authors: Yeli, Ravi Kumar; S B, Dhanya; H C, • Sunil Abstract: Spinal dysraphism, characterized by incomplete closure of neural and bone spinal structures, manifests as congenital fusion abnormalities along the dorsal midline, involving the skin, subcutaneous tissue, meninges, vertebrae, and neural tissue. Magnetic resonance imaging (MRI), the preferred imaging modality for assessing spinal dysraphism across all age groups, provides direct visualization of the spinal cord without the need for contrast or ionizing radiation while also eliminating bone artifacts and allowing multiplanar imaging. The objective of this study was to evaluate the range of spinal dysraphism lesions and assess the significance of MRI in their evaluation. Methodology Thirty patients with suspected spinal dysraphism underwent evaluation at the Medical College Hospital and Study Centre in Vijayapur, India. This cross-sectional observational study included patients diagnosed or provisionally diagnosed with spinal dysraphism based on clinical and imaging profiles. Cases were identified through preliminary findings on radiographs. Results The study encompassed individuals aged one month to 20 years, with the largest proportion of patients (36.67%) falling within the 1-5-year age group. Spina bifida was the most prevalent spinal abnormality, accounting for 70% of cases. In 12 patients (40%), the most prevalent location of involvement was the lumbosacral spine. Conclusion MRI provides excellent tissue differentiation, particularly of lipomatous tissue, with reproducible and comprehensive section planes and relative operator independence. Moreover, MRI is beneficial for children with suspected spinal dysraphism as it can be performed without ionizing radiation, biological risks, or the need for intrathecal contrast media.

Title: Sonographic evaluation of male anterior urethral abnormalities in tertiary hospital in Bangalore: Cross sectional study Authors: Muchchandi1, Rajashekhar; Takalaki, *, Nandini Abstract: Background: The present study titled is intended to evaluate the role of sonourethrography in the investigations of male anterior urethral abnormalities. The present study was conducted with two objectives, To find out the role of sonourethrography in the evaluation of male anterior urethral lesions. Comparison of sensitivities of ascending urethrography and sonourethrography, in detection of anterior urethral lesions Materials and Methods: Source of data: Source of data collection is from patients referred to department of radiology, Sapthagiri institute of medical sciences and research Centre College, Bengaluru, Karnataka with voiding difficulties. Method of collection of data: Patients presenting with voiding difficulties were examined by conventional radiographic retrograde urethrogram followed by sonourethrogram. Results :- 40 subjects were selected for the study. All the 40 patients underwent RGU and SUG Pathology detection rates of RGU was 58% and Pathology detection rates of SUG 63%Stricture detection rates of RGU was 83% whereas in SUG it was 100% Urethritis detection rates of RGU was 83% whereas in SUG it was 100% Diverticulae detection rates of RGU and SUG was 100% Periurethral cysts detection rates of RGU was 50% and whereas in SUG it was 100%

Title: A study to know etiology and spectrum of MRI findings in patients with seizures in tertiary care hospital, Karnataka Authors: Muchchandi, Rajashekhar; Takalaki, , Nandini Abstract: Background And Objectives: Seizure is a common medical disorder and neuroimaging plays valuable role in evaluation of etiological factors for seizures. The objectives are to identify structural abnormalities in the brain that may be associated with the cause of seizures with MRI and to study the spectrum of findings in patients with seizures. Materials and Methods:- All the cases referred to department of radiology, Sapthagiri institute of medical sciences and research Centre College, Bengaluru, Karnataka. All MRI scans were performed on a 1.5 T Philips Achieva. Sequences used , T1WI sagittal, T2WI axial and coronal, FLAIR axial, gradient echo axial, DWI axial and ADC maps, T1W with contrast, MRA and MRS according to MR Imaging protocol of seizures. Results: In our study 60 patients with clinical diagnosis of seizures were selected as per the criteria laid down by ILAE 1981.Majority of the subjects 28.3% were in 1-15yrs age group, followed by 20% were in 16-30yrs age group, 16.7% were in <1yrs and 31-45yrs age group. Male 35 (58.33%) and Female 25(41.64%).The MR examination revealed pathological findings in 30 out of 60 patients (50%) which includes, cerebral infarct with gliosis (20%), NCC (6.66%), atrophy (6.66%), gliomas (1.66%), cortical malformations (3.34%),tuberculoma (3.34%),venous thrombosis (3.34%), cavernoma (3.34%), meningioma (1.66%)
