摘要

Magnetic Resonance Imaging, by far, has been found to be the most sensitive and non-invasive method for detecting angiographic images on the circle of Willis. The length of the vessels which form part of the circle of Willis is important for neurosurgeons while they perform various neurological procedures. It also helps the radiologists in interpreting the angiographic images in a better way. The length of the vessel also affects the haemodynamics of the vessel, thus affecting the major role of the circulus arteriosus as an anastomotic channel. Though many studies have been conducted on cadavers to measure the length of various cerebral vessels, not much work has been done on the length of the vessels by using modern techniques like MRI. The vessel length in the circle of Willis on MRI has not been reported, especially in this region of north India. This study was conducted on 120 normal angiographs which were taken by magnetic resonance angiographic techniques. In the results which were obtained in the present study, the length of the vessel was found to be higher on the left side. The range of the length on the right side was 10.4mm - 27.54mm, the mean length being 15.78mm ± 3.71mm, whereas on the left side, the range of the length was 10.6mm - 31.96mm and the mean length was 17.37mm ± 4.84mm . The present study gave the length of the anterior cerebral artery according to the side. In view of this, the length which is presented here may provide reference values which are specific to the three dimensional time of flight MRI angiography and it may be of value in the investigation of other pathologic features of the circle of Willis.
