(MIP) Angiography (Doppler) images can be processed by Maximum Intensity Projection to interactively create different projections. Although the maximum intensity projection (MIP) post processing algorithm is sensitive to high signal from inflowing spins as used in MRI, it is also sensitive to high signal of any other etiology as used in ultrasound imaging. The MIP connects the high intensity dots of the blood vessels in three dimensions, providing an angiogram that can be viewed from any projection. Each point in the MIP represents the highest intensity experienced in that location on any partition within the imaging volume.
For complete interpretation the base slices should also be reviewed individually and with multiplanar reconstruction (MPR) software. The MIP can then be displayed in a CINE format or filmed as multiple images acquired from different projections.

(OPG) The Oculoplethysmography is used to detect a hemodynamically significant stenosis of the carotid circulation, by measuring the arrival times of pulses in the eye and ear. Indirectly the blood flow in the ophthalmic artery is measured, which branches off the carotid artery and supplies blood to the eye. A delay between pulse arrival in the eye and ear is an indication of a hemodynamically significant stenosis in the vessel whose corresponding pulse is delayed.
Other ultrasound or angiography procedures are necessary to confirm the diagnosis and have also replaced this technique.
