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 research progress of CT related to esophageal varices of cirrhotic patients complicated with portal hypertension.MethodsRelevant CT literatures of esophageal varices of cirrhotic patients complicated with portal hypertension were collected to make an review,then summarized the research status and progress of CT in the diagnosis and evaluation of lower esophageal varices.ResultCT had a good correlation with endoscopic diagnosis of esophageal varices, and CT was of great value in evaluating the presence, degree, and risk of esophageal varicose veins, especially in predicting the risk of esophageal varicose veins, which could be used as an effective modality to assist endoscopic examination to a certain extent.ConclusionsCT is an important examination method for esophageal varices, which has important value in diagnosis and evaluation. In the future, more further researches can be carried out to provide more strong and accurate support for the diagnosis and treatment of esophageal varices.
Objective To summarize the CT, MRI, and positron emission computed tomography (PET) imaging findings of hematologic malignancies of the pancreas, so as to improve the capacity of its diagnosis. Methods After searching articles concerning radiological research about hematologic malignancies of the pancreas, summarizing its imaging characteristics. Results Hematologic malignancies of the pancreas include pancreatic lymphoma, pancreatic multiple myeloma, myeloid sarcoma, posttransplantation lymphoproliferative disorder, and giant lymph node hyperplasia. ① Pancreatic lymphoma: imaging features of pancreatic lymphoma are segmental or diffuse homogeneous enlargement of the pancreas, diameter of mass >5 cm, adenopathy below the level of renal veins, and lack of pancreatic duct dilation. Blurred margins of pancreas by lymphadenopathy is highly suggestive of lymphoma. ② Pancreatic multiple myeloma: pancreatic multiple myeloma are hyperintense on both T1- and T2-weighted images. ③ Pancreatic granulocytic sarcoma: pancreatic granulocytic sarcoma present as homogeneous hypoenhancing mass on CT, usually without pancreatic duct dilation. On MRI, the lesions are isointense and mildly hyperintense on T1- and T2-weighted images respectively. ④ Posttransplantation lymphoproliferative disorder: diameter of leison of posttransplantation lymphoproliferative disorder usually is >5 cm with poor enhancement. Lesions are mildly hyperintense on T2-weighted images and extremely hypermetabolic on PET images. ⑤ Giant lymph node hyperplasia: it mainly appear as solitary noninvasive masses. Punctate calcification and surrounding supply vessels are observed in hyaline vascular type. Plasma cell type demonstrate unapparent enhancement and less calcification. Conclusions Hematologic malignancies of the pancreas manifest different imaging features on CT, MRI, and PET. Familiarity with such characteristics helps to early recognize diseases and determine next-step measures.
ObjectiveTo investigative current status and hotspot issues of pancreatic cancer imaging research.MethodsThe literatures focusing on pancreatic cancer and published from 2001 to 2020 were retrieved from the core database of Web of Science. The quantitative analysis of literatures was then conducted by using the CiteSpace software based on the bibliometric method. The research trend was then summarized systematically and the potential research fronts and focuses were explored.ResultsA total of 2111 articles in the field of pancreatic cancer imaging research were retrieved. The clustering of co-citation of pancreatic cancer included vascular resection, irreversible electroporation, autoimmune pancreatitis, sporadic pancreatic cancer, sarcopenia, pancreas, stereotactic body radiation therapy, metastatic pancreatic cancer, familial pancreatic cancer, abdominal ultrasonography, fibroblast, early diagnosis, time trends in survival, radiomics, pancreatitis, gemcitabine, concurrent chemoradiotherapy, adjuvant chemotherapy, and microbubbles. The burst keywords in the field of pancreatic cancer after 2016 included FOLFIRINOX, skeletal muscle, sarcopenia, and texture analysis. The hot keywords clustering had prognosis, fine needle aspiration, positron emission tomography, vascular invasion, angiogenesis, unresectable, liver transplant, extend pancreatectomy, transplantation, paclitaxel, metastatic colorectal cancer, colorectal cancer, microsatellite stable, radiomics, hospital volume, occult metastasis, risk factor.ConclusionIt might be the trend of imaging research to study the prognosis, risk factors, and quantitative sarcopenia of pancreatic cancer by using radiomics.
