“…Additionally, independent samples t-test was carried out on the acquisition time to analyze the differences between conventional vascular imaging technique and compressed sense technique in terms of scan time. Correlation analysis was used to investigate the impact of different types of cerebral vascular lesions on the acquisition time [18].…”

In recent years, Compressed Sense technology has emerged as a promising image reconstruction method, demonstrating great potential in reducing data acquisition time and improving image quality. This study aims to explore the application of compressed sense technology in cerebral magnetic resonance angiography (MRA), compare it with conventional vascular imaging techniques, and evaluate its advantages in clinical practice. The study utilized a Philips Ingenia 3.0T magnetic resonance imaging (MRI) system and included a certain number of normal subjects and patients with cerebral vascular lesions. Both conventional vascular imaging techniques and compressed sense technology were employed for scanning, and the differences between the two methods in terms of image quality, acquisition time, and other aspects were compared. Image quality assessment indicators included overall image quality, blood vessel display clarity, and blood vessel contrast, among others. Additionally, the application of both techniques in specific clinical cases was analyzed. The results showed that, compared to conventional vascular imaging techniques, compressed sense technology significantly shortened the scanning time while ensuring image quality. In the detection of certain diseases such as cerebral aneurysms and ischemic cerebrovascular lesions, compressed sense technology not only effectively improved the clarity and contrast of blood vessel display but also made the detection process more convenient and accurate. Moreover, for patients with severe movement disorders or those who cannot tolerate long scanning times, compressed sense technology is a more suitable choice. In conclusion, compressed sense technology exhibits significant advantages in cerebral MRA. It demonstrates clear advantages over conventional vascular imaging techniques in terms of image quality, acquisition time, and other aspects, and it has high application value in the detection of specific diseases. We recommend the extensive application of compressed sense technology in clinical practice and further exploration of its application in other areas of MRI imaging.

“…In comparison of the frequently used image modality for acute abdomen (PAR, ultrasound [US], CT), several studies had discussed the pros and cons of each modality. 8,14,15 CT has the most accurate and reproducible diagnosis to acute abdomen, but it has higher cost, lower availability, and high radiation exposure. On the contrary, US and PAR have lower diagnostic sensitivity but lower cost and higher accessibility.…”

“…1–7 The 2017 Royal College of Radiologists iRefer guidelines for PAR only lists a few indications for PAR, including bowel obstruction and constipation. 8 However, due to some reasons, such as financial concerns or difficult access to the advanced instruments, many hospitals still choose PAR for preliminary diagnosis. For patients whose PAR shows an imaging finding (eg, bowel dilatation, free air, abnormal calcifications, or soft tissue density) or who exhibit severe symptoms, an abdominal computed tomography (CT) scan is additionally performed.…”

Background: Plain abdominal radiography including supine and erect abdominal radiographs (SAR and EAR) is a frequently used image modality for preliminary evaluation of acute abdomen. We aimed to explore which one of the SAR or EAR has a higher diagnostic value in overall diagnosis of acute abdomen, including their respective advantages over each other for the various underlying diseases. Methods: We retrospectively analyzed the imaging findings of plain abdominal radiography of patients with acute abdomen who received abdominal computed tomography (CT) within 24 hours at the emergency department of a medical center in northern Taiwan between October 2019 and February 2020. Final diagnosis was made by CT reports and clinical data. The relevance between the imaging findings and clinical diagnosis in the groups of SAR and EAR were compared. Results: A total of 1009 cases with acute abdomen were included, of which 341 (33.8%) underwent EAR and 668 (66.2%) underwent SAR. Among them, 820 cases had final diagnosis confirmed by CT and clinical data. In comparison of the diagnostic relevance of SAR and EAR, there were no significant difference in the overall acute abdomen, but EAR showed a better diagnostic relevance in cases with bowel obstruction than SAR did (100% vs 87.2%, p < 0.05). No statistical difference in other abdominal diseases. Conclusion: There is no significant difference between SAR and EAR in evaluation of overall acute abdomen. However, EARs has a diagnostic advantage over SAR for evaluation of suspected bowel obstruction.
