腹部放射線（画像）診断学において、「Abdominal Radiology」誌がとても役立ちますよ、ということを以前お話ししましたが、最新号の「Volume 49, Issue 9 September 2024」から下記論文を紹介します。
「Imaging features of perinephric myxoid pseudotumors of fat. (Abdominal Radiology 2024;49(9): 3107–3116.)」
高分化型脂肪肉腫などと鑑別を要する腎周囲脂肪の異常な変化を呈する偽腫瘍が紹介されています。
「A pictorial essay of PI-RADS pearls and pitfalls: toward less ambiguity and better practice. (Abdominal Radiology 2024;49(9):3190–3205.)」
PI-RADS評価時の様々なピットフォールを学べます。
結果は、下記の通りです。
Compared with MRKHS, the CAIS group showed significantly detectable vagina, more ventrally located nodular and cystic structures, fewer cysts within the cystic structures, and nodular structures with higher signal intensity on DWI and lower ADC values.
