Dose measurements were taken from four SPECT/CT and four PET/CT cameras commercially available from different manufacturers. A calibrated ionization chamber was placed in whole-body or head phantoms for the acquisition of CT images with clinically used parameters. Computed tomography dose index (CTDIvol) values were calculated according to the IEC 60601-2-44:1999 formula. The measured CTDIvol doses were compared with those preprogrammed by the manufacturer. In the case of the whole-body phantom, the differences between the measured and displayed values varied between −31 and +24% [European document RP162 (2012) sets up the limit for acceptance criterion as ±20%]. The head phantom data showed either an agreement between −10 and +24%, or an underestimation by two-fold. The latter seemed to be because, while preprogramming the doses, the manufacturer had used the whole-body phantom instead of a proper head phantom. The results of the work demonstrate the need for individual dosimetric calibration of every single X-ray tube. Dosimetric checks should be included in the regular quality control programmes of the SPECT/CT and PET/CT devices. Special attention should be paid to head-and-neck and paediatric protocols, in which the use of a head phantom is recommended for dose calibration. © 2014 Wolters Kluwer Health | Lippincott Williams & Wilkins LA - English DB - MTMT ER - TY - JOUR AU - Várkonyi, Tamás AU - Fehértemplomi, Katalin AU - Takács, Róbert AU - Lengyel, Csaba Attila AU - Lázár, M AU - Papós, Miklós AU - Pávics, László AU - Kempler, P AU - Wittmann, Tibor TI - Determinants of impaired gastric emptying in type 2 diabetic patients.
