Computed tomography (CT) and magnetic resonance imaging (MRI) are enabling more precise diagnosis and treatment planning in patiensts with diseases of the larynx. The aim of this article is to describe the role of these methods in assessment of the laringeal diseases and key local anatomic characteristics important for spread of the disease. CT and MRI have a valuable contribution to the staging of the tumors due to the possibility to show the relationship to the ventricular complex, involvement of the subumucosal spaces, defining craniocaudal and anterposterior extension, laringeal cartilage invasion, as well as regional lymph node metastases.

Magnetic resonance cholangiopancreatography (MR CP) is a relatively new, noninvasive method in patients with pancreaticobiliary diseases, which is comparable to invasive endoscopic retrograde cholangiopancreatography (ERCP). One of the most common indications for MRCP is malignant obstruction of the bile and pancreatic ducts. Standard imaging protocol includes routine abdominal study followed by a sequence for MRCP adapted to each of the patients and site of the malignant process. MRCP is a simple to perform, does not exposure the patients to radiation, requires no anesthesia, is less operator dependent and allows better visualization of ducts proximal to an obstruction. Thus, during one examination only, it is possible to assess not only pancreaticobiliary system but also abdominal structures, which increases diagnostic value of MR and is therefore, optimal method in evaluation of these patients.

AIMS: To evaluate diagnostic accuracy of pretreatment surgical magnetic resonance images (MRI) in assessment of patients with tumors of the larynx. MATERIALS AND METHODS: The study included 12 patients, 11 men and 1 women, age 61,4 years. All patients underwent laryngeal endoscopy and biopsy followed by MRI. The biopsy confirmed that all patient had squamous-cell carcinoma. The MRI images were evaluated for presence in supraglottic, glottic or subglottic region, invasion of submucosal space, cartilage, extension to extralaryngeal tissue, presence of regional lymph nodes in regions I to VII. Imaging data were compared to surgical findings. RESULTS: In 11 patients (92%) the tumor was supraglottic and glotic region and in 1 (8%) subglottic. None of them had tumor only in one region. Paraglottic ivasion was seen in 9 (75%) and preepiglottic in 2 (50%) patients. Paraglottic and preepiglotic invasion in the same time was seen in 3 (25%) patients. 7 (58%) patients had normal vocal cord mobility, 3 (25%) mobility was unilateral and 2 (17%) had no vocal cord mobility. Cartilage invasion has not been seen in present study. All patients had billateral limphadenopathy region II-IV. Extension to extralaryngeal tissue was absent. These findings were confirmed on surgery with high diagnostic accuracy. CONCLUSION: MRI has been shown to be a reliable method for presurgical assessment of patients with tumor of the larynx.
