Patients were advised to hold their breath during the scan. Scanning parameters were: slice collimation 2 × 128 × 0.6 mm by means of a z-flying focal spot, gantry rotation time 280 ms, and tube potential 100 kV or 120 kV based on a body mass index (BMI) cutoff of 25 kg/m 2 [23, 24]. Attenuation-based tube current modulation was used with a
CT Scan adalah salah satu peralatan radiodiagnostik dengan menggunakan sinar-x, yang pada dasarnya gambar yang dihasilkan merupakan pemetaan dari penyerapan objek terhadap sinar-x. Teknologi terbaru MSCT 128 Slices Dual Sources merupakan teknologi pencitraan radiologi diagnostik paling mutakhir.

Method. Objective methods for converting tube-current-modulation protocols between CT scanners were developed. Three CT scanners were investigated, a GE LightSpeed 16 scanner, a GE VCT scanner, and a Siemens Definition AS+ scanner. Translation of the automatic exposure control (AEC) parameters such as noise index or quality reference mAs across
Low-Dose CT. In the mid and late 1990s, investigators in Japan ( 30) and the United States ( 31) demonstrated the potential benefits of low-dose CT screening for lung cancer. Numerous Japanese, U.S., and European studies quickly followed ( 32 – 38 ). Lung cancer was found in 0.9%–2.7% at initial (prevalence) screening ( 30, 31, 33 – 35
