Eur Radiol: What is the impact and significance of renal mass texture analysis in different stages of kidney CT?

At this stage, the method of using texture analysis (TA) to evaluate kidney masses has been used in many studies and proved effective.

Kidney CT scans include plain scan (NECT) phase, cortical medulla (CM) phase, and nephrography (NG) phase.

Recently, a study published in the journal European Radiology compared the texture analysis of solid renal masses in the plain scan (NECT) phase, cortical medulla (CM) phase, and nephrography (NG) phase in kidney CT scan schemes ( The difference in TA) characteristics and diagnostic performance clarify which phase should be used as the best phase for diagnosis.

A total of 177 cases of solid renal masses were included in this study (116 cases of renal cell carcinoma: 51 cases of clear cell carcinoma, 40 cases of papillary cell carcinoma, 25 cases of chromophobe cell carcinoma.

    The results of texture analysis are different in the subjective and quantitative evaluation of renal masses in different CT enhancement phases.

    The results of texture analysis are different in the subjective and quantitative evaluation of renal masses in different CT enhancement phases.
When comparing masses and distinguishing cc-RCC from other masses, the cortical medullary stage has the highest differential diagnosis value.
When combining data from patients using different CT scan schemes for research, the differences in texture analysis features used for the diagnosis, grading and staging of kidney masses should be analyzed more carefully, because these differences are not only related to the tumor itself, It is also related to the different phases of CT.
