In recent years, cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have been increasingly used for the treatment of peritoneal metastases. Imaging examination plays an important role in the process of CRS+HIPEC in treatment of peritoneal metastasis. This article briefly introduces the preoperative imaging evaluation, postoperative imaging evaluation, and current limitations of CRS+HIPEC in the treatment of peritoneal metastases.
The radiology diagnosis report encapsulates radiologists’ comprehensive analytical insights and deep interpretive understanding of patients’ imaging data, serving as an essential basis for disease diagnosis, clinical treatment planning, and prognosis assessment. As the primary medium through which radiologists contribute substantively to patient’s care, traditional free-text reports represent subjective interpretations shaped by individual experience and stylistic preferences. Such reliance on personal factors can introduce inconsistencies and limitations in clinical applications. To address these challenges, structured radiology reporting has been developed. We present a concise overview of the origins, developmental trajectory, current landscape, and emerging trends of structured radiology reports, highlighting their role in advancing standardized.
Acute pancreatitis is a prevalent acute abdominal syndrome in clinical practice, characterized by a complex and variable course, numerous complications, high treatment challenges, and significant variability in prognosis. Imaging computed tomography (CT) plays an indispensable role in the diagnosis, classification, and severity assessment of acute pancreatitis. To ensure precise communication of the condition across departments and mutual recognition of imaging examination results among different medical institutions, there is an urgent need to establish standardized imaging reports for acute pancreatitis. We present the CT structured reporting for acute pancreatitis utilized at West China Hospital of Sichuan University, with the aim of promoting the standardization of CT report writing for acute pancreatitis.
ObjectiveTo summarize the common imaging features of liver cancer after local-regional therapy in order to more accurately evaluate the post-treatment response of it. MethodThe literatures of studies on imaging features after ablation, transcatheter therapy, and radiotherapy of liver cancer in recent years were searched and reviewed. ResultsIt was not accurate to evaluate the response of liver cancer after treatment only by comparing the size of tumor before and after treatment. We should follow up and observe the changes of enhancement components after tumor treatment, and pay attention to identify the normal features after treatment. ConclusionsImaging evaluation after local-regional therapy of liver cancer is of great significance in management and clinical decision-making of patients with liver cancer. Standard response evaluation systems such as EASL or mRECIST should be carefully applied after local-regional therapy of liver cancer. Treatment response of patients should be comprehensively evaluated in combination with the characteristics of local-regional therapy methods and timing, so as to avoid delaying timing of secondary treatment and causing excessive treatment.
Objective To investigate the situation and prospect of local recurrence of rectal cancer by using CT and MRI. Method Relevant references about the imaging diagnosis of local recurrence of rectal cancer， which were published domestic and abroad in recent years， were collected and reviewed. Results In the diagnosis of local recurrence of rectal cancer， the sensitivity of CT was higher than that of MRI， while the specificity and accuracy were not. Perfusion CT， dynamic contrast-enhanced MRI， and diffusion weighted imaging were valuable in diagnosing local recurrence of rectal cancer， as new diagnostic techniques. Conclusion Both CT and MRI are important and valuable methods in diagnosing for local recurrence of rectal cancer.
Objective To summarize the application and prospect of susceptibility weighted imaging （SWI） in diagnosis of hepatic disease. Methods The application of SWI in diagnosis of hepatic disease was analyzed retrospectively via reviewed the literatures home and abroad, and to look forward to the future of the clinical values of SWI. Results A number of hepatic diseases such as cirrhosis, hematochromatosis， and malignant tumors could induce iron overload in hepatic cell and Kuffper cell. Because of SWI is sensitive to vein， vascular abnormality, haemorrhage （including all kinds of metabolities after bleeding）， iron overload， calcification, and so on, so the use of SWI in hepatic disease is explored continually. Conclusions SWI may be a new method for diagnosis of hepatic disease, which can supply more valuable information for clinician.
ObjectiveTo summarize the methods and research progress of imaging evaluation of liver iron concentration.MethodsThe current status and progress of different imaging techniques in liver iron overload research were reviewed by studying the relevant literatures at home and abroad. The methods for determining liver iron concentration and their advantages and disadvantages were summarized.ResultsThe imaging methods for determining liver iron concentration mainly included traditional non-enhanced CT and dual energy CT examination, magnetic resonance signal intensity ratio, relative signal intensity index, T2 and R2 values, magnetic resonance spectroscopy, T2* and R2* values, susceptibility weighted imaging, and quantitative susceptibility mapping.ConclusionLiver iron quantification imaging method, including dual-energy CT and magnetic resonance imaging could non-invasively and accurately assess the liver iron overload.
ObjectiveThis review has summarized in detail the advances in computed tomography (CT) and magnetic resonance imaging (MRI) imaging in evaluating the efficacy of targeted therapy for gastrointestinal stromal tumor (GIST).MethodsTo summarize the image-related guidelines, consensus, international conference reports, and relevant knowledge of clinical research on the evaluation of the efficacy of GIST targeted therapy in recent years.ResultsThe CT and MRI manifestation after targeted treatment of GIST was closely related to pathological changes, including necrosis, cystic degeneration, and bleeding. CT was the preferred imaging method. Functional magnetic resonance imaging, such as diffusion weighted imaging (DWI), had made some progress. The main criteria for evaluating the efficacy of GIST targeted therapy were RECIST 1.1 and Choi criteria.ConclusionCT and MRI play an important role in evaluating the efficacy of targeted therapy for GIST.
Objective To evaluate the sensitivity， specificity, and accuracy of magnetic resonance imaging （MRI） in characterizing adnexal masses. Methods The databases such as the Cochrane Library, PubMed， EMbase， CNKI， and WanFang Data were searched on computer from 1991 to 2011. The reviewers screened the trials according to inclusion and exclusion criteria strictly, extracted the data， and assessed the methodology quality. Meta-analysis were performed using the Metadisc 1.40 software. The acquired pooled sensitivity, specificity， and summary receiver operating characteristic curve （SROC） were used to describe the diagnostic value. The pooled likelihood ratios were calculated based on the pooled sensitivity and specificity. Results Ten case-control studies involving 649 women who were suspected to have pelvic masses were included and 729 masses were confirmed by the postoperative histopathology. The pooled statistical results of meta-analysis showed that：the sensitivity and specificity of MRI were 〔89%（84%-92%）， P=0.046 6〕 and 〔87% （83%-90%）， P=0.000 2〕 respectively, the positive and negative likelihood ratios of MRI were 6.25（P=0.008 5） and 0.14（P=0.029 1） respectively, and the area under the SROC curve （AUC） was 0.941. The sensitivity and specificity of ultrasound were 〔87%（82%-91%）， P=0.000 0〕 and 〔73%（69%-77%）, P=0.000 0〕 respectively, the positive and negative likelihood ratios of MRI were 3.07（P=0.000 0） and 0.18（P=0.000 1） respectively， and the AUC was 0.897. The speci?city and accuracy of MRI in characterizing female pelvic masses were higher than ultrasound obviously. Conclusion According these evidences， the MRI should be recommended to the women who are suspected to have pelvic masses as a preferred.
