The objective of our retrospective institutional experience is to report the overall response rate, R0 resection progression-free survival, and safety/toxicity neoadjuvant FOLFIRINOX (5-fluorouracil [5-FU], oxaliplatin, irinotecan, leucovorin) chemoradiation in patients with locally advanced pancreatic cancer (LAPC). Patients LAPC treated were identified via Massachusetts General Hospital Cancer Center pharmacy database. Demographic information, clinical characteristics, safety/tolerability...
<h3>Importance</h3> The efficient and accurate interpretation of radiologic images is paramount. <h3>Objective</h3> To evaluate whether a deep learning–based artificial intelligence (AI) engine used concurrently can improve reader performance efficiency in interpreting chest radiograph abnormalities. <h3>Design, Setting, Participants</h3> This multicenter cohort study was conducted from April to November 2021 involved radiologists, including attending thoracic radiology fellows, residents,...
The purpose of this study was to retrospectively compare the diagnostic adequacy lung scintigraphy with that pulmonary CT angiography (CTA) in care pregnant patients suspected embolism.Patient characteristics, radiology report content, additional imaging performed, final diagnosis, and were recorded for consecutively referred or CTA according physician preference. Measurements arterial enhancement performed on all images patients. Lung studies deemed inadequate diagnosis at time image...

We aimed to evaluate the longitudinal stability of left common iliac vein (LCIV) compression by right artery on magnetic resonance venography (MRV).This retrospective study included 214 patients diagnosed with May-Thurner syndrome MRV. identified a subset who underwent contrast-enhanced cross-sectional imaging pelvis six months before or anytime after MRV and did not undergo any interventional venous procedures between two studies; 36 met these criteria. The degree was calculated in both...
Cancers that arise in ovarian or extraovarian endometriosis are a distinct disease category with histologic profile different from of the more common epithelial cancers and better prognosis. Because malignant transformation endometriomas is rarely associated lymphadenopathy peritoneal carcinomatosis, high index suspicion on part radiologist necessary to establish timely diagnosis endometriosis-related allow appropriate oncologic management. Although imaging not currently performed for...
The purpose of this study was to establish CT criteria as an indication for colonoscopy in patients with acute diverticulitis.The composed diagnosed diverticulitis on contrast-enhanced (CECT) from January 2000 December 2004. Patients without subsequent were excluded. Findings correlated patient outcomes over follow-up. Sensitivity, specificity, and predictive values the imaging parameters prediction colon cancer calculated. Outcomes also compared between men women.Of 1034 a diagnosis...
To investigate the predictive factors for a non-diagnostic result and final diagnosis of pulmonary lesions with an initial on CT-guided percutaneous transthoracic needle biopsy.All biopsies performed over 4-year period were retrospectively reviewed. The pathological results classified into three categories-malignant, benign, non-diagnostic. A was defined when no malignant cells seen specific benign could not be made. demographic data patients, lesions' characteristics, technique,...
The internet is an important source of medical information for many patients and may have a key role in the education about lung cancer screening (LCS). Although most LCS programs United States informational websites, accuracy, completeness, readability these websites not previously been studied.To evaluate content US program websites.This cross-sectional study assessed identified on September 15, 2018. A standardized checklist was used to assess each website, text analyzed reading level,...
RSNA expert consensus guidelines provide a framework for reporting CT findings related to COVID-19, but have had limited multireader validation.To assess the performance of and quantify interobserver variability in application patients undergoing chest suspected COVID-19 pneumonia.A retrospective search from 1/15/20 3/30/20 identified 89 consecutive scans whose radiological report mentioned COVID-19. One positive or two negative RT-PCR tests were considered gold standard diagnosis. Each scan...
BACKGROUND. Previous studies compared CT findings of COVID-19 pneumonia with those other infections; however, to our knowledge, no date have included noninfectious organizing (OP) for comparison. OBJECTIVE. The objectives this study were compare chest features COVID-19, influenza, and OP using a multireader design assess the performance radiologists in distinguishing between these conditions. METHODS. This retrospective 150 examinations patients (mean [± SD] age, 58 ± 16 years) diagnosis or...
Background: Lung cancer screening (LCS) with low-dose computed tomography (LDCT) helps early lung detection, commonly presenting as small pulmonary nodules. Artificial intelligence (AI)-based vessel suppression (AI-VS) and automatic detection (AI-AD) algorithm can improve of subsolid nodules (SSNs) on LDCT. We assessed the impact AI-VS AI-AD in classification SSNs [ground-glass (GGNs) part-solid (PSNs)], LDCT performed for LCS.
A method of morphometric analysis jejunal mucosa using computer-aided microscopy is described. It based on the technique interactive computer graphics with definition by observer areas and lengths for measurement, but it also includes automatic measurements grey-level segmentation. The analyses are performed rapidly efficiently. applicable to biopsy tissue from many sites.
To determine the prevalence and severity of tracheomalacia in adults with cystic fibrosis (CF) by using dynamic cine multidetector computed tomography (CT) to correlate these findings pulmonary function test (PFT) results parenchymal lung disease.In this institutional review board-approved HIPAA-compliant study, 40 patients CF (22 men, 18 women; mean age, 28 years +/- 8 [standard deviation]; age range, 18-54 years) prospectively underwent PFTs, standard thin-section CT, two CT acquisitions....
To determine the relationship of increasing body mass index (BMI) and abdominal fat on effective dose acquired from computed tomography (CT) abdomen pelvis scans.Over 6 months, dose-length product total milliamp-seconds (mAs) routine CT scans 100 patients were recorded. The performed a 64-slice scanner by using an automatic exposure control system. Effective (mSv) based product, BMI, periumbilical thickness, intra-abdominal documented for each patient. compared with dose.Thirty-nine men 61...
To determine the clinical role, safety, and diagnostic accuracy of percutaneous transthoracic needle biopsy in evaluation pulmonary consolidation.A retrospective review all computed tomography (CT)-guided biopsies (PTNB) at a tertiary care hospital over 4-year period was performed to identify cases PTNB for consolidation. For each case, CT Chest images were reviewed by two thoracic radiologists. Histopathologic microbiologic results obtained follow-up performed.Thirty 1090 (M:F 17:30, mean...
