    Abstract
  •   Objective  To compare the effect of multi-slice spiral CT enhanced scan and MRI in the differential diagnosis of renal parenchymal tumours.  Methods  A total of 140 patients with renal tumours in our hospital from December 2017 to December 2020 were selected as the research objects. All cases were examined by multi-slice spiral CT enhanced scan and MRI. The results of histopathological examination were taken as the gold standard, and the diagnostic efficiency of the two methods in the differential diagnosis of different pathological types and different lesion sizes of renal tumours were statistically analysed.  Results  No significant difference was observed in the sensitivity, specificity and accuracy of multi-slice spiral CT enhanced scan (88.68%, 85.29% and 87.86%) and MRI (90.57%, 82.35% and 88.57%) (χ2=0.203, 0.108, 0.034; P=0.652, 0.742, 0.853). Moreover, no significant difference was observed in the sensitivity, specificity and accuracy of multi-slice spiral CT enhanced scan (95.45%, 92.31% and 94.74%) and MRI (97.73%, 92.31% and 96.49%) in the qualitative diagnosis of renal parenchymal tumour with diameter>4 cm (χ2=0.345, 0.000, 0.209; P=0.557, 0.999, 0.647). The sensitivity, specificity and accuracy of multi-slice spiral CT enhanced scan and MRI in the qualitative diagnosis of renal parenchymal tumour with diameter < 4 cm (83.87%, 80.95% and 83.13%) were not significantly different from those of MRI (85.48%, 76.19% and 83.13%, χ2=0.345, 0.141, 0.000; P=0.557, 0.707, 0.999).  Conclusion  Multi-slice spiral CT enhanced scan detection and MRI detection have high clinical application value for the diagnosis of renal parenchymal tumours, and have high differential diagnosis efficiency for small renal parenchymal tumours. Clinical diagnosis can be reasonably selected according to the actual situation of patients.
