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 47, issue 11, November 2022」から下記3論文を紹介します。

「Polyethylene glycol-based gels for treatment of prostate cancer: pictorial review of normal placement and complications. (Abdominal Radiology 2022;47(11):3847–3854.)」
前立腺癌への放射線治療を行う際に、放射線の直腸への影響を低減する目的「直腸周囲ハイドロゲルスペーサ・SpaceOAR」が留置されます。これがどのような画像所見を呈するかを知っておいたほうがよいでしょう。

「Added value of gadolinium-based contrast agents for magnetic resonance evaluation of adnexal torsion in girls. (Abdominal Radiology 2022;47(11):3868–3882.)」
本論文では、下記のように結論づけられています。
Post-contrast sequences did not provide additional benefit in evaluating acutely torsed ovaries but helped in excluding torsion in patients with adnexal lesions. Therefore, contrast administration should be individualized, potentially reserved only for those with abnormal ultrasound or pre-contrast images.

「Multimodality imaging findings of infection-induced tumors. (Abdominal Radiology 2022;47(11):3930–3953.)」
多岐にわたる感染誘発腫瘍を学ぶことが出来ます。
