Abstract:
Two cases of haemorrhage during cranial computed tomography (CT) occurring during the enhancement phase of CT examination immediately after the administration of intravenous contrast medium are reported. In both cases, the preceding unenhanced scansshowed evidence of haemorrhage. The risk of aneurysmal rupture as a result of retching and vomiting induced by intravenous contrast is stressed. Judicious use of contrast enhanced CT is suggested in patients with suspected aneurysmal subarachnoid haemorrhage.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
