肾实性肿瘤MRI诊断研究进展

Progress of research on CT and MRI diagnosis of solid renal tumors

肾实性肿瘤的预后取决于组织学亚型。近年来,由于影像技术的进步,肾实质性肿瘤特别是小肿瘤的检出率及诊断准确率明显提高。而肾脏肿瘤中,约20%是良性肿瘤,可以保守治疗,但大多数是肾恶性肿瘤,由于其恶性或有恶性潜能,需要及时诊断及治疗。据统计,小于4cm以下的肾脏肿瘤大部分都是影像学检查被偶然发现的,因此,针对肾脏的影像学检查对肿瘤的检出非常重要。本文主要讨论磁共振成像(MRI)检查技术对肾实性肿瘤的诊断研究进展。

The prognosis of solid renal tumors is up to histological subtypes.In recent years,along with the progress of imaging technologies,the detection rates and diagnosis accuracy rates of solid renal tumors,especially small tumors,are apparently improved.About 20%of renal tumors are benign tumors and conservative treatment is feasible.However,most are malignant renal tumors or potentially malignant ones,so timely diagnosis and treatment are necessary.According to statistics,most renal tumors below 4cm are detected occasionally in image examinations,so image examinations of kidney are very critical for the detection of tumors.This paper mainly discusses the progress of research on MRI examination technologies for diagnosis of solid renal tumors.
