Per the American College of Radiology (ACR), it is not appropriate to report magnetic resonance imaging (MRI) brain codes for the axial source images acquired as part of a magnetic resonance angiography (MRA) study.  The axial source images are an integral portion of the MRA examination.  While some lesions may be visible on the MRA axial source images, these images are specifically designed to minimize brain parenchymal resolution in order to optimize visualization of the vasculature.

 Only when a full and complete brain MRI is performed separate from a full and complete MRA examination (separate data set acquisition) would it be appropriate to report both an MRI and MRA code.
