Abstract

PURPOSE: To evaluate the detectability of contrast enhancing lesions, initially demonstrated in standard prone dynamic contrast enhanced MRI (DCE-MRI), in a supplementary supine breast MRI examination performed following the standard prone DCE-MRI examination and to show the correlation of spatial displacement of the lesions with breast size and density.

 

METHODS: Forty-two patients with 45 lesions were prospectively evaluated. Supine breast MRI was acquired with a 6-channel body coil following a standard DCE-MRI in prone position after the repositioning of the patient. No additional contrast media was administered. Images were evaluated by two radiologists in consensus for the visibility of the lesions. Lesion localization relative to the sternal midline, chest wall and nipple was measured in both prone and supine positions. Correlations between lesion displacement and breast size or breast density were analyzed.

 

RESULTS: Twenty-three (52.3%) of 45 lesions were masses, 22 (47.7%) were non-mass enhancements (NME). Forty-four lesions (97.8%) could be detected on supine images. One linear NME of 33 mm in length could not be seen on supine images. Twenty (46.5%) of the detected lesions in supine position were equal or smaller than 10mm (11 NME (55%) and 9 masses (45%)). Lesion displacement relative to the chest wall increased with increasing breast size (P < 0.001).

 

CONCLUSION: An abbreviate supine sequence following a standard prone DCE-MRI with single contrast media administration is an effective method in defining the lesion location on supine position.
