Mri of the hypopharynx with provocative maneuvers
The purpose of this study was to assess the validity of magnetic resonance (MR) functional images of the hypopharynx. Following T2-weighted spin-echo sequences during quiet respiration, contrast enhanced 2D-Turbo-FLASH sequences were obtained during Valsalva-maneuver, quiet respiration, A- and U-pho...

| description | The purpose of this study was to assess the validity of magnetic resonance (MR) functional images of the hypopharynx. Following T2-weighted spin-echo sequences during quiet respiration, contrast enhanced 2D-Turbo-FLASH sequences were obtained during Valsalva-maneuver, quiet respiration, A- and U-phonation, respectively. Tumor detection was clearly improved using functional MRI (sensitivity of 97.4%, specificity 83.3%, accuracy 95.5%) when compared with MRI during quiet respiration (sensitivity of 87.1%, specificity 33.3%, accuracy 80%). Rapid MR sequences such as 2D-Turbo FLASH allow functional imaging of the hypopharynx, thereby improving MR diagnosis of hypopharyngeal tumors. |
