ABSTRACT
Objective To assess the application value of NCE-MRA using iMSDE prepared bSSFP sequence in lower limb in patients with diabetes. Methods This prospective study included a total of 35 patients with type II diabetes who underwent CE-MRA on the 1.5T MR scanner after the NCE-MRA. The obtained MIP images were independently rated by two radiologist with a four score table and using CE-MRA as a reference standard to evaluate the diagnostic accuracy of NCE-MRA for the narrowed arteries. The difference of the percent age of diagnostic arterial segments between NCE-MRA and CE-MRA on diabetic patients was evaluated by the χ2 test. Results Compared with CE-MRA, the diagnostic-value arterial segment ratio of pelvic arteries on NCE-MRA is decreased significantly. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of two readers in NCE-MRA were 95%/87%, 96%/95%, 57%/72%, 99%/99%, and 96%/95%(k=0.76), respectively. Conclusions The NCE-MRA using iMSDE prepared bSSFP sequence is capable of depicting vascu-lar lesions for the lower extremities in diabetic patients with the advantages of contrast agent free, short scan times and good diagnostic value in the thigh and calves.
