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.
ObjectiveTo summarize the status and progress of imaging studies of pancreatic neuroendocrine neoplasms (pNENs).MethodThe relevant literatures published recently at domestic and abroad about the imaging of pNENs were collected and reviewed.ResultsDue to poor visibility of pancreatic body and tail, the application of ultrasound (US) was limited. Compared with US, endoscopic ultrasound (EUS) and contrast-enhanced ultrasound (CEUS) could improve the detection rate of pNENs. The ability of plain CT scans to differentiate pathological grades was still controversial, but the value of enhanced scan was higher. CT texture analysis was feasible in the discrimination of nonhypervascular pNENs and pancreatic ductal adenocarcinoma (PDAC). Teta2 was the parameter with the highest diagnostic performance. The enhanced features of MRI were similar to CT. Combined with the apparent diffusion coefficient (ADC) value, the diagnostic and classification capabilities of MRI were improved, and the sensitivity and specificity of different ADC thresholds were also different. 68Ga-tetraazacyclododecane tetraacetic acid (68Ga-DOTA) peptide PET-CT had good preliminary diagnostic value for well-differentiated pNENs, and 18Fluoro-fluorodeoxyglucose (18F-FDG) PET-CT had limited diagnostic value.ConclusionsSomatostatin receptor imaging is of high diagnostic value and can guide clinical treatment and predict prognosis, but it has not been widely used in China. Conventional morphological images have advantages in the diagnosis and classification of pNENs. Therefore, it is important to choose a proper image inspection method.
Objective To summary the principle of magnetic resonance spectroscopy imaging and its application progress in diagnosis and differential diagnosis of pancreatic cancer. Methods The newest related literatures of home and abroad were collected and reviewed. Results Magnetic resonance spectroscopy imaging was a technology using the magnetic resonance phenomena and chemical shift phenomena to measure molecular organization. The spectroscopy most commonly used in clinical and scientific research includes 1H， 31P， and 23Na. Conclusion Magnetic resonance spectroscopy as the only approach to noninvasive quantitative provding biochemical information in vivo， has an important significance to the diagnosis and differential diagnosis of pancreatic cancer.
Objective To investigate the magnetic resonance imaging （MRI） assessment and functional evaluation of chronic pancreatitis （CP）. Methods Literatures about MRI assessment of CP （especially the evaluation of pancreatic exocrine function with MRI） were reviewed. Results Some early parenchymal changes （pancreatic size，signal intensity of pancreas， and enhancement pattern） in the CP could be visualized by MRI；ductal changes could be visualized by MR cholangiopancreatography （MRCP）；and secretin-stimulated MRCP （combination of both morphologic and functional evaluation） not only improved the visualization of pancreatic duct and side branches，but also allowed evaluation of the pancreatic exocrine function noninvasively. Secretin-stimulated diffusion weighted imaging also could be used as a noninvasive method to assess pancreatic exocrine function. Conclusions Conventional MRI and （or） secretin-stimulated MRI can become valuable means in CP （especially early-stage CP）， with furnishing morphologic and functional information simultaneously. However，further research is needed to verify the diagnostic accuracy of these modalities.
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 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.
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.
