Role of multi-detector CT in staging of Colorectal carcinoma – A correlative study.

Aim: To study the CT characteristics of wall thickening in case of benign and malignant lesions of the colon and rectum, to evaluate the role of MDCT in pre-operative tumour stanging of colorectal malignancies and to evaluate the effectiveness of MDCT in differentiating benign and malignant colorectal lesions. Material and methods: It was correlative study done on patients with wall thickening involving the colon and rectum on CT were included. CT was performed using 16 slice SIEMENS SOMATRON Emotion CT scanner. CT findings were finally correlated with histopathology. Results: Patients with complaints of loose stools, vomiting, weight loss, constipation, bleeding PR, abdominal pain were evaluated by CT scan and which showed findings that were highly suggestive findings of malignancy like bowel wall thickening, presence of lymph nodes, peri-colic fat standing, infiltration of adjacent viscera and presence of metastases. Conclusion: MDCT is an excellent modality in the diagnosis and differentiation of benign and malignant lesions of the colon and rectum. MDCT is also useful in the staging of maligant lesions of the colon and rectum. MDCT is also useful in the staging of malignant lesions which helps in proper planning of surgery and further management of the patient.

Radiological analysis of interstitial lung diseases.

Aims and objectives: To diagnose interstitial lung diseases using HRCT and chest X-Ray and to study and compare the different radiography patterns evident in both conventional chest radiography and HRCT. Material and method: The present study was a prospective and observational (non interventional) type of study. This study aimed evaluating patients coming to the Radiology Department of Dhiraj General Hospital, by using X-RAY and CT scan so as to achieve aims and objectives outlined. Results: Of the 48 patients, 28 patients were males (58.33%) and 20 (41.67%) were females. The age of the patients ranged from 39 years to 80 years. The common diseases included in the study were idiopathic pulmonary fibrosis (25%), idiopathic NSIP (16.5%), rheumatoid arthritis (14.5%), lymphangitis carcinomatosis (8.33%). Conclusion: In our study, 48 patients were radiologically evaluated with X - ray and CT-Scan. Chest X is a primary modality used to screen patients with lung pathologies, being cheap, easy to perform and requires less radiation. HRCT is the modality of choice for diagnosis of interstital lung diseases.
