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.
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.
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.

Conclusion Each method gets its own advantage even computed tomography seems like dominated on the detection and diagnosis pancreatic cancer, moreover, magnetic resonance imaging has been improved rapidly in recent years which shows its enormous potential.
ObjectiveTo investigate the radiological appearances of postoperative complications after living donor liver transplantation for patients with hepatocellular carcinoma under multi-detector row spiral computed tomography (MDCT) and magnetic resonance imaging (MRI) examination. MethodsThirty-nine imaging data in 20 patients with hepatocellular carcinoma after living donor liver transplantation from January 2008 to June 2010 in the West China Hospital were included and analyzed by two radiologists respectively. The relations between the types of complications and radiological appearances were especially recorded. ResultsAll the cases experienced complications to different extent. Common surgical complications occured in 20 cases, including pertitoneal fluid collection (14 cases), pneumoperitoneum (2 cases), swelling of peritoneum, omentum, and mesentery (1 case), abdominal wall swelling (2 cases), pleural effusion (9 cases), and pericardial fluid collection (2 cases). Hepatic vascular complications involved hepatic artery in 3 cases, portal vein in 5 cases. Biliary complications presented in 7 cases, including anastomotic stenosis of biliary duct (6 cases) and bile leak (1 case). Graft parenchymal complications included intrahepatic lymph retention (11 cases), infarction (3 cases), and infection (2 cases). Intrahepatic recurrence in 5 cases, intraperitoneal metastasis in 3 csses and pulmonary metastasis in 2 cases. ConclusionMDCT and MRI have important diagnostic values for postoperative complications after living donor liver transplantation for patients with hepatocellular carcinoma.
ObjectiveTo assess the feasibility of intravoxel incoherent motion diffusion-weighted imaging (IVIM) in evaluating microvessel density (MVD) and microvascular invasion (MVI) of hepatocellular carcinoma (HCC).MethodsRat models were established to be scanned by IVIM. HCC lesions corresponding to IVIM image were examined pathologically to get data of MVD and MVI. Spearman correlation analysis was used to compare the apparent diffusion coefficient (ADC), D, D*, and f with MVD, independent samples t test was used to compare ADC, D, D*, and f between MVI (+) and MVI (–) groups.ResultsFifty HCC lesions were included finally. ADC and D values both showed a negative correlation with MVD (r=–0.406, P=0.003; r=–0.468, P=0.001), D* and f showed no statistical correlation with MVD (P=0.172, 0.074, respectively). The differences in ADC and all the IVIM parameters (D, D*, and f) between MVI (+) and MVI (–) HCCs were not statistically significant (P=0.393, 0.395, 0.221, 0.550).ConclusionADC and D can be used to evaluate MVD of HCC, but ADC and IVIM parameters were limited in evaluating MVI.
Objective To probe CT grading criteria of vascular invasion in pancreatic cancer. Methods Retrieved articles in CNKI and PubMed about value of CT in preoperative assessment of vascular invasion in pancreatic cancer last ten years. Results Multislice helical CT is considered the best imaging method to assess the invaded peripancreatic vessels in pancreatic cancer. There are different CT criteria of vascular invasion in pancreatic cancer based on extension of hypodense tumor and its relation to blood vessels, on the degree of circumferential contiguity of tumor to vessel, on the degree of lumen stenosis, and on the degree of contiguity between tumor and vessels combined vascular caliber. Conclusion CT grading criteria are not uniform, each one has defects.
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.
