Breaking through tradition: A new study on the 125I seeds implantation assisted by the puncture angle guidance device

Precision Medical Sciences, EarlyView.
This study showed the puncture angle guide device assisted 125I seeds implantation is safe and feasible. Compared with the manual deployment of needles, the puncture time, the number of puncture needle adjustments, and the number of intraoperative CT scans are significantly reduced, which can be used in clinical applications.

One‐year follow‐up after fractionated ultra‐high‐dose‐rate FLASH radiotherapy in patient with extramammary Paget disease of the scrotum

Precision Radiation Oncology, EarlyView.
An elderly male patient with extramammary Paget disease of the scrotum and multiple metastases was treated with fractionated FLASH‐RT (40 Gy in 5 fractions) in the scrotal lesion. Abstract Objective Ultrahigh‐dose‐rate radiotherapy (FLASH‐RT) has been shown to reduce radiation‐induced normal tissue injury in preclinical studies.
