Computed Tomography (CT) Sample Clauses
Computed Tomography (CT). Figure 2.15 The principle of applanation tonometry. The artery is partially compressed against a hard structure. The small (0.5mm in diameter) sensor detects the force of the artery wall. Accessed 2012 (▇▇▇▇▇.▇▇▇▇▇▇▇▇▇▇▇▇▇▇.▇▇▇). Aortic PWV is measured as: Aortic PWV = Distance m/s Transit time The Philips Precedence single-photon emission computed tomography (SPECT)/CT 16- Slice multi-detector (MDCT) system (Philips Healthcare, Best, Netherlands) was used for scans of the chest and abdomen (Figure 2.17). The scanner is capable of performing non- diagnostic, unenhanced CT for the purpose of quantifying VC. The precedence SPECT/CT performs Spiral/helical scanning which is characterised by a continuous gantry rotation and continuous data acquisition while the scan couch is moving at constant speed. In the present study a scan field of view (SFoV) of 50cm was required to include both the chest and abdomen incorporating the carotid to the femoral arteries. The camera has a rotation speed of 0.5s. The radiation dose for this scan was 5mSv; moderately lower than a diagnostic CT scan used in routine clinical practice with radiation doses ranging between 10 – 15mSv.
Computed Tomography (CT). CT is mostly used for staging, CT should be performed with oral and intravenous contrast material during the venous phase of enhancement. Positive oral contrast material is useful for bowel wall implants and negative oral contrast material is useful for calcified tumor implants (▇▇▇▇▇▇-▇▇▇▇▇ et al., 2018).
Computed Tomography (CT). All CT exams will be on a scheduled and/or prepped basis during Regular Hours. Any inpatient exam will be performed late in the afternoon.
