Dr. Pushkar Bansal | |
Background: The larynx is composed of a sequence of mucosal folds supported by a cartilaginous framework. The present study was conducted to compare CT and MRI in the diagnosis of laryngeal carcinoma. Materials &Methods: 76patient aged 18 to 60 years of laryngeal carcinoma of both genders were selected. All MR imaging tests were performed using a 3T MR imaging system. A 128-slice CT scanner operating in dual-energy CT mode 27 was used to perform CT scans. Results: Out of 76 patients, 40 were males and 36 were females. Histopathology showed 76 (100%), CT assessed lesions in 72 (94.7%) and MRI in 81 (96%) of laryngeal carcinoma cases. The sensitivity of CT was 98.4, specificity was 95.6 and positive predictive value (PPV) was 96.2. The sensitivity of MRI was 93.6, specificity was 89.7, and positive predictive value (PPV) was 94.4. Conclusion: Although laryngeal cancer can be detected more accurately using a CT scan, MRI and CT may be similar techniques. |
