Radiomics-Based Deep Learning Prediction of Overall Survival in Non-Small-Cell Lung Cancer Using Contrast-Enhanced Computed Tomography.

Patient outcomes of non-small-cell lung cancer (NSCLC) vary because of tumor heterogeneity and treatment strategies. This study aimed to construct a deep learning model combining both radiomic and clinical features to predict the overall survival of patients with NSCLC. To improve the reliability of the proposed model, radiomic analysis complying with the Image Biomarker Standardization Initiative and the compensation approach to integrate multicenter datasets were performed on contrast-enhanced computed tomography (CECT) images.

A noninvasive index to predict liver cirrhosis in biliary atresia.

Background: Biliary atresia is a progressive obliterative cholangiopathy affecting both extrahepatic and intrahepatic biliary trees, resulting in fibrous obliteration of the biliary tract and subsequent development of cirrhosis.

Objective: The aim of this study was to find noninvasive indices to predict the status of hepatic fibrosis in children with biliary atresia.

Materials And Methods: We retrospectively measured the volume of the hepatic lobes and spleen from MR images, obtained biochemical data and analyzed the relationship between the imaging and biochemical indices, and the pathological status of hepatic fibrosis in 35 children with biliary atresia.

Using volume index and lateral hepatic angle to differentiate biliary atresia from TPN-associated cholestasis.

Objectives: Differential diagnosis between biliary atresia (BA) and total parenteral nutrition-associated cholestasis (TPN-AC) and early treatment for cholestatic infants are challenges for evaluating neonatal or infantile cholestasis. The aim of our retrospective study was to apply noninvasive indices of magnetic resonance images to differentiate BA from TPN-AC.

Methods: A total of 44 patients diagnosed as having BA (n = 30) or TPN-AC (n = 14) were included in the present retrospective study and underwent abdominal magnetic resonance imaging to evaluate the possibility of BA.

Less-invasive MR indices of clinically evident esophageal variceal bleeding in biliary atresia patients.

Background/purpose: Esophageal variceal hemorrhaging is potentially life threatening for long-term survivors of biliary atresia. We evaluated the feasibility of less-invasive parameters for predicting the presence of clinically significant esophageal variceal bleeding in biliary atresia patients.

Methods: A total of 30 patients aged 108-5314 days (median = 285 days) with biliary atresia underwent a magnetic resonance examination with fast spin-echo T2-weighted imaging and spin-echo, T1-weighted images with fat saturation after use of a contrast medium on a 1.

Effects of propranolol on the left ventricular volume of normal subjects during CT coronary angiography.

Objective: The purpose of this study is to determine the effects of propranolol on the left ventricular (LV) volume during CT coronary angiography.

Materials And Methods: The LV volume of 252 normal Chinese subjects (126 subjects with propranolol medication and 126 age- and gender-matched Chinese subjects without medication) was estimated using 64 slices multi-detector CT (MDCT). The heart rate difference was analyzed by the logistic linear regression model with variables that included gender, age, body height, body weight, systolic blood pressure (SBP), diastolic blood pressure (DBP) and the dosage of propranolol.

Hepatic ADC value correlates with cirrhotic severity of patients with biliary atresia.

Introduction: At least 40% of survivors of biliary atresia have progressive cirrhosis even after undergoing Kasai operation. The values of hepatic apparent diffusion coefficient and apparent-diffusion-coefficient-related indices were applied to biliary atresia patients and correlated with cirrhotic severity scores of model for end-stage liver disease or pediatric end-stage liver disease model, Child-Turcotte, and Child-Pugh systems.

Materials And Methods: Thirty-three biliary atresia patents (mean=1140, 61-4314 days of age) received magnetic resonance image examinations due to complications of biliary atresia from April 2008 to August 2009.

Morphine- and glucagon-augmented magnetic resonance cholangiopancreatography to evaluate living liver donors.

The purpose of this study was to investigate the effectiveness of the combined use of intravenous morphine and intramuscular glucagon in improving magnetic resonance cholangiopancreatography (MRCP) image quality in donors for living-related liver transplantation. Sixteen healthy donor candidates underwent an MRCP study. Coronal, single-shot, fast spin-echo, heavily T2-weighted dynamic MRCP images were obtained before and 3 minutes after the intravenous administration of morphine HCl with a dose of 0.

Enterolith ileus in a patient with jejunal diverticulosis: sonographic findings.

Jejunal diverticula are rare. Enterolith ileus, the least-encountered complication among patients with jejunal diverticula, is incidentally found at surgery or during imaging studies such as radiography, CT, or endoscopy. We report the case of a 71-year-old man with enterolith ileus involving the jejunum that was initially detected using abdominal sonography and subsequently confirmed with abdominal CT and surgery.

Adrenomyeloneuropathy, a dynamic progressive disorder: brain magnetic resonance imaging of two cases.

Adrenomyeloneuropathy (AMN) is a phenotype variant of X-linked adrenoleukodystrophy. We present two patients with adult-onset AMN who were initially suspected to have demyelinating disorders radiologically and finally diagnosed on the basis of laboratory data. The brain magnetic resonance images showed abnormal signal intensity at pyramidal tracts and cerebellar hemisphere bilaterally with abnormal enhancement after contrast medium administration.

Intraductal papillary carcinoma of bilateral breasts: a case report.

We report a 59-year-old woman presenting with a 2-month history of occasional bloody discharge from her right nipple and a palpable right breast mass on self-examination. The mammography revealed heterogeneously dense fibroglandular stromas of bilateral breasts, a lobulated mass in her right breast associated with faint pleomorphic microcalcifications, and, in addition, very faint focal granular microcalcifications in the left breast. Breast ultrasound revealed a lobulated and heterogeneous hypoechoic tumor with irregular margins at the right breast and a well-circumscribed tumor with heterogeneous echotexture at the left breast.

Mesenteric lipoblastoma: case report.

We present a rare case of mesenteric lipoblastoma in a 16-month-old girl. The US, CT and MRI features of this unusual tumour are described and correlated with the pathology findings. MRI more clearly suggested the presence of fat components in the tumour.
