Background: Although measles epidemic has been controlled effectively after measles vaccination being carried out, China is still the focus of measles epidemic. The lower respiratory tract infections (LRTIs) is the most common complication, and also the most common reason for the death of patients with measles.
Purpose: To analyze what clinical factors could affect the grades of LRTIs in children under five years old with measles.
Objective: To investigate the clinical value of spectral CT in diagnosis of negative gallstones and common bile duct stones primarily.
Methods: All patients diagnosed with negative biliary stones were analyzed and examined by spectral CT scanner retrospectively. Based on acquired raw imaging data, image series were reconstructed as described below: the optimal contrast-to-noise ratio monochromatic energy images, calcium- and fat- based material decomposition images and spectral curve images.
