| description | Tujuan kajian ini dijalankan adalah untuk menguji ketepatan teknik "3D time of
flight" magnetic resonans angiografi berbanding dengan teknik "intra-arterial digital subtraction" angiografi untuk pengimejan segmen-segmen arteri didalam "circle of
Willis".
Seramai 38 orang pesakit yang telah menjalani kedua-dua
ujian "3D TOF MRA" dan "IADSA" di Hospital Universiti Sains Malaysia mulai November I 998 hingga Disember 2000 telah dimasukkan ke dalam kajian ini. Daripada jumlah ini, sebanyak 398 segmen-segmen arteri telah dibandingkan dan dianalisa. Dua orang pemerhati telah menjalankan analisis secara retrospektif terhadap imej-imej
"IADSA" dan imej-imej "MlP" dari "3D TOF MRA" pada masa yang berlainan. Segmen-segmen AI, A2, MI dan Pl telah dikategorikan sebagai nonnal, kecil atau tidak wujud, manakala segmen-segmen ACOM dan PCOM telah dikategorikan sebagai berfungsi, "patent" ataupun tidak kelihatan.
The purpose of this study is to compare the accuracy of 3D time of flight magnetic
resonance angiography (3D TOF MRA) with intraarterial digital subtraction angiography
(IADSA) in depicting the arterial segments of the circle of Willis.
38 patients who had underwent both 3D TOF MRA
and IADSA examinations in Hospital Universiti Sains Malaysia from November 1998 to
December 2000 were included in this study giving a total of 398 arterial segments
compared and analysed. Two observers performed blinded retrospective analysis of the
IADSA images and MIP display of the 3D TOF MRA of the circle of Willis on separate
sessions. The AI, A2, Ml and PI segments were depicted as normal calibre, small or
absent while the ACOM and PCOM segments were depicted as functional, patent or not
visualised.
