Purpose: The manual delineation of organs at risk is a process that requires a great deal of time both for the technician and for the physician. Availability of validated software tools assisted by artificial intelligence would be of great benefit, as it would significantly improve the radiation therapy workflow, reducing the time required for segmentation. The purpose of this article is to validate the deep learning-based autocontouring solution integrated in syngo.

Due to the increased risk of recurrent deep venous thrombosis when left in place, IVCF removal is indicated once anticoagulant treatment can be reintroduced. However, many temporary IVCF are not removed.

- Retrievable inferior vena cava filters (IVCF) were developed to reduce the risk of recurrent deep vein thrombosis compared to permanent filters.
- A study of 85 patients who underwent IVCF retrieval found that intrafilter thrombi were present in 81% of cases, while 88% had venous wall fragments.
- Despite these findings, the presence of thrombi or fragments did not correlate with an increased risk of recurrent venous thromboembolism or death within three months after retrieval.
Objective: To evaluate feasibility, safety and efficacy of a combination of screw fixation and cementoplasty for pathologic bone fracture.
Methods: In this single-center prospective study, all consecutive percutaneous screw fixations under assisted CT guidance for palliation and fracture treatment of pathologic bone fracture were reviewed from July 2019 to February 2021. The primary outcome measure was the procedures' technical success, defined as the correct placement of the screw(s), without any complications.
Secondary lesions and hemopathy localized in sternal bone may be responsible for persistent pain and resistant to classical analgesics. Surgical treatment is not applicable in these cases. We report on 2 cases of sternal osteosynthesis by internal cemented screw fixation, under fluoroscopy and CT scan control, without complication and with clear, immediate reduction of pain.
