CT-Scan vs MRI in Diagnosing Laryngeal Carcinoma

Abstract

Background: MRI imaging offers more sensitivity than CT to cartilage invasion but results in a high rate of false-positive studies which decreases their overall accuracy. The objective is to compare accuracy of CT scan vs MRI in the laryngeal carcinoma. Subjects and Methods: All patients have been diagnosed, with and without contrast, including neck MRI and CT. In order to prevent invalidation, before laryngeal biopsy, MRI and CT scanning have been done such that the images are not altered by peri tumorous inflammation. Results: The MRI classification was right for 20 out of 25 patients (80 percent) and 5 outsized cases: three cT1b lesions were pT1a and two cT1a lesions were squamous cell papilloma’s during pathological examination. CT was accurately identified in 17 out of 25 patients (68%), with 8 understated cases: 3 cT1a lesions by CT were pT1b, 3 cT1a lesions were pT3, and 2 tumours had not been found in the CT scan. Conclusion: Our research showed that MRI in preoperative stage early glottic cancer is more sensitive than CT to accurately select eligible patients for conservatory larynx surgery like super cricoid laryngectomy and cordectomy.
