Back to the future: sagittal CT in the evaluation of COPD.

Objectives: To identify features of obstructive airway disease on sagittal reconstruction, compare the accuracy of findings to traditional imaging characteristics of COPD, and determine the fraction of additional cases identified using new characteristics.

Methods: The study was approved by the centre's Institutional Review Board and is HIPAA compliant. Two hundred sixteen patients with HRCT and spirometry within a 3-month window were included.

Comparative risk of recurrence of dysplasia and carcinoma after endoluminal eradication therapy of high-grade dysplasia versus intramucosal carcinoma in Barrett's esophagus.

Background: Endoscopic therapy is the preferred approach for the management of Barrett's esophagus (BE) patients with high-grade dysplasia (HGD) and intramucosal carcinoma (IMC). Little is known about outcome differences in patients with HGD versus IMC.

Objective: To determine and compare the rate of recurrent dysplasia or neoplasia in patients with HGD or IMC undergoing endoscopic therapy.
