The invention relates to the field of
medical imaging, and in particular relates to a
head and neck angiography method. The
head and neck angiography method comprises the following steps of: (1), obtaining the basic data of an examined person including the sex, the age, the
heart rate, the systolic pressure and the diastolic pressure; (2), substituting the obtained basic data of the examined person into a PT time calculation formula; (3), determining the scanning /
exposure time T through a defined scanning range; (4), obtaining the total injection time according to the PT time and the exposuretime T, selecting the
injection rate of a contrast agent to be 3.0-5.0 ml / s, and obtaining the total injection amount and the total amount of the contrast agent by calculation; and (5), setting the
delay time to the PT time on a CT
scanner, starting the
exposure key of the CT
scanner and a contrast agent
injector at the same time, injecting the total amount of the contrast agent, then, continuously injecting the total amount of normal
saline injection, and performing
exposure by the CT
scanner, so that an examination image is obtained. The
head and neck angiography method in the invention is used for improving the imaging effect of blood vessels; the use amount of the contrast agent is used in a personalized manner; therefore, the
radiation dosage is reduced; and the
radiation injury of
radiography on a patient and the rate of
allergic reaction are reduced.
