Methods and Materials
The study was based on the prospective analysis of MRI images in a series of 40 patients (90% males),
overall average age 62.2 ± 5.1 years; range 49–70 years,
who underwent MRI imaging prior to the surgery.
The study was done in the Center for Radiology and MRI and the Clinic for ENT and Maxillofacial Surgery,
Clinical Center of Serbia in 2009 and 2011.
Upon admittance to the hospital,
all patients had clinical examination including indirect laryngoscopy,
endoscopic examination with biopsy,
followed by MRI.
Based on these findings they were all planned for surgery.
All patients gave formal written consent for all diagnostic and therapeutic procedures.
Those who refused the surgery or had contraindications for general anesthesia underwent radiotherapy.
All MR imaging studies were obtained at Siemens Avanto 1.5 T and included turbo spin-echo images (TSE) sequence in T1w image in axial plane (TR/TE 450/11),
T2w in axial,
coronal and sagittal planes (TR/TE 4200/72) and T2w FS in axial plane (fat saturation,
TR/TE 4980/72) before and T1w in axial and coronal planes (TR/TE 596/11) after intravenous administration of gadolinium contrast.
MR images were evaluated for tumor localization (supraglottis,
glottis,
subglottis),
infiltration of paraglottic and preepiglottic space and deeper structures of the neck. Results of MR image analysis were compared to surgical findings.
