    Abstract Background: End-to-end dosimetry audit for brachytherapy is challenging due to the steep dose gradient. However, it is an efficient method to detect unintended errors in actual clinical practice.
    Purpose: We aimed to develop an on-site end-to-end test phantom for three-dimensional image-guided brachytherapy (IGBT) for cervical cancer.
    Methods: The test phantom we developed consisted of a water tank with an applicator/detector holder. The holder was designed to accommodate the applicator and insert an ionization chamber (PinPoint; PTW, Freiburg, Germany) to measure the dose at point A. Imaging and reconstruction were performed in the same way as performed for a patient. The feasibility of our test phantom was assessed in two different hospitals using tandem and ovoid (made of either metal or carbon) applicators that the hospitals provided.
    Results: The measured and calculated doses at point A were compared for each applicator. We observed that the values obtained using metal applicators were consistently lower, on an average by -2.3%, than the calculated values, while those obtained using carbon applicators were comparable to the calculated values. This difference can be attributed to the attenuation of the dose by the metal applicators, resulting in a lower dose at point A. The majority of treatment planning system, including the one used in this study, do not account for the material of applicator.
    Conclusions: An end-to-end test phantom for IGBT was developed, tested, and applied in a dosimetry audit in hospitals and showed favorable results for evaluating the point A dose.

  4. Article ; Online: Safety and Effectiveness of Endovascular Treatment of Complications Associated with Persistent Sciatic Artery: A Qualitative Systematic Review.

    Abstract Purpose: To conduct a systematic review to evaluate the safety and efficacy of endovascular treatment with stent grafts (SGs) for complications associated with persistent sciatic artery (PSA).
    Materials and methods: The MEDLINE, Web of Science, Scopus, and Ichushi Web databases were searched to identify articles focusing on endovascular treatment with SGs for complications associated with PSA published from inception to 15 September 2023. The review included 31 case reports, 2 case series, and 7 conference proceedings. Forty patients (median age: 67 years, range: 22-88 years; 25 women) with 41 limbs underwent endovascular treatment with 65 SGs for ischemia (n=26), aneurysm (n=13), and trauma (n=2). Prior treatments were systemic anticoagulation (n=7), thrombolysis (n=5), thrombectomy in (n=3), and amputation (n=1), while concurrent treatments were thrombolysis (n=6) and thrombectomy (n=2). The median number of SGs implanted was 2 (range: 1-4). Early outcomes were technical success and complications. Late outcomes were primary patency, secondary patency, freedom from re-intervention, and clinical success.
    Results: The technical success rate was 100%. Intervention-specific complications were reported in 4 cases, but there were no major adverse events. The clinical success rates at 1 and 2 years were 100% and 95.7%, respectively. The primary patency rates at 1 and 2 years were 81.5% and 67.6%, respectively, and the secondary patency rates at 1 and 2 years were 94.5% and 81.6%, respectively.
    Conclusion: Endovascular treatment with SGs for complications associated with PSA is safe and effective, with acceptable mid-term patency and durability, and is recommended as the first-choice treatment.

    Abstract Aims: Dynamic stress computed tomography (CT) perfusion is a non-invasive method for quantifying myocardial ischemia by assessing myocardial blood flow (MBF). In this meta-analysis, we evaluated the diagnostic accuracy of dynamic CT perfusion for the detection of significant coronary artery disease (CAD) across various CT scanners, obese patients, and its prognostic value.
    Methods and results: We systematically searched PubMed, Embase, Web of Science, and Cochrane library for published studies evaluating the accuracy of CT myocardial perfusion in diagnosing functional significant ischemia by invasive fractional flow reserve. The diagnostic performance of dynamic CT perfusion in detecting ischemia was evaluated using a summary receiver operating characteristic (sROC) curve. A total of 23 studies underwent meta- analysis. In myocardial region without ischemia, MBF was measured at 1.44 ml/min/g (95% confidence interval [CI]: 1.13-1.75), while in region with ischemia, it was 0.94 ml/min/g (95% CI: 0.80-1.08) (p<0.001). On the patient-based analysis, the area under the sROC curve of CT-MBF was 0.93, with a sensitivity of 0.84 and specificity of 0.88. Differences in CT type (dual source vs. single source), and body mass index (BMI) did not significantly affect the diagnostic performance. The pooled hazard ratio of dynamic CT perfusion for predicting adverse events was 4.98 (95%CI: 2.08-11.93, p=<0.001, I2=61%, p for heterogeneity = 0.07).
    Conclusions: Dynamic CT perfusion has high diagnostic performance in the quantitative assessment of ischemia and detection of functional myocardial ischemia as defined by invasive FFR, and may be useful in risk stratification of CAD patients.
