Breath holding does not eliminate motion of the diaphragm. Changes in the motion of the diaphragm and transthoracic pressure during a breath hold result in complex movement of the heart and may cause blurring during breath-hold MR imaging.

The majority (93%) of HAPE-only lesions that are occult at T2-weighted and portal and/or equilibrium phase MR imaging are nonneoplastic, even in patients with pathologically proved HCC.

Contrast-enhanced T1-weighted imaging can be used as a stand-alone sequence for the diagnosis of HCC in patients with cirrhosis prior to liver transplantation.

In community-based radiology practice, mammography screening with 3D DBT yielded lower recall rates, an increased CDR for cancer overall, and an increased CDR for invasive cancer compared with 2D DM. The PPV1 was significantly greater in the group screened using 3D DBT.
