In vivo detection of choline in ovarian tumors using 3D magnetic resonance spectroscopy.

Objectives:To assess the clinical feasibility of 3-dimensional (3D) proton magnetic resonance spectroscopy (MRS) of ovarian masses at 1.5 T.Materials and Methods:We prospectively evaluated 16 patients with 23 ovarian masses using contrast-enhanced magnetic resonance imaging and 3D chemical shift ima
