Background: Since 1984 MRI gel dosimetry has been introduced as a potential technique for 3D dosimetry. Most of the studies have measured R1 (1/T1) or R2 (1/T2) properties of the gel depending on the gel type. We have studied image intensity change in the Fricke gel by different MRI protocols. Materials and Methods: Gel Dosimeters contain 0.4 mM ferrous sulphate, 1 mM NaCl, 50 mM H2SO4 and 1% b...

OBJECTIVE Molecular breast imaging techniques, such as breast-specific gamma imaging, are increasingly being used as adjunctive diagnostic technologies to mammography and ultrasound. This multicenter clinical patient registry was designed to quantify the impact of this modality on the management of the breast patient population in clinical practice and to identify the subgroups of patients bene...
