COMPARISON OF 3 MM × 3 MM VERSUS 6 MM × 6 MM OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY SCAN SIZES IN THE EVALUATION OF NON–PROLIFERATIVE DIABETIC RETINOPATHY

Comparison of 3 mm versus 4 mm rigid endoscope in diagnostic nasal endoscopy☆

Objective Compare nasal endoscopy with 3 mm versus conventional 4 mm rigid 30° endoscopes for visualization, patient comfort, and examiner ease. Methods Ten adults with no previous sinus surgery underwent bilateral nasal endoscopy with both 4 mm and 3 mm endoscopes (resulting in 20 paired nasal endoscopies). Visualization, patient discomfort and examiner's difficulty were assessed with every ...

Fracture detection in the cervical spine with multidetector CT: 1-mm versus 3-mm axial images.

BACKGROUND AND PURPOSE Multidetector CT imaging of the cervical spine performed with submillimeter collimation allows for the production of excellent quality multiplanar reformations and reconstructed axial images at any chosen section thickness. Currently there is no consensus on what images need to be reviewed for accurate diagnosis of cervical spine fractures. Our study assesses whether 1-mm...

Vlba Imaging at 7 Mm and Linear Polarimetric Observations at 6 Cm and 3 Mm of Sgr A* 1. 7 Mm Vlba Imaging of Sgr A*

We summarize the results of 7 mm VLBA imaging of Sgr A* and discuss some of the diiculties of accurately constraining the size of Sgr A* with VLBI observations. Our imaging results are fully consistent with the hypothesis that the VLBA image of Sgr A* is a resolved elliptical Gaussian caused by the scattering of an intervening thermal plasma. We show that determination of the minor axis size at...
