“…RUSH-CT scanning protocols are preplanned and work semiautomatically, reducing scanning time by 57 % in this preliminary clinical study. Several reports have described standardized CT scanning protocols [8,12], but to our knowledge there have been no other reports to date that deal with preplanned, semiautomated protocols.…”

Aim: The purpose of this study was to develop a fast scanning protocol for spiral CT of emergency trauma patients (RUSH-CT) in order to accelerate the diagnostic work-up. Method: In a consecutive series 446 trauma patients underwent spiral CT; of these, 51 emergency patients underwent a modified protocol (RUSH-CT) on a recent technology scanner (Somatom Plus 4). Scanning time was compared between the RUSH-CT and the regular protocols. Results: The average time for RUSH-CT, comprising one pilot scan and three spiral scans, including preparation time and monitor reading was 15 min (range 12±18 min; n = 51). Using regular organ protocols comprising two pilot scans and four spiral scans, the control group had an average scanning time of 35 min. In comparison to the conventional organ protocols, total scanning time could be reduced by the RUSH-CT by 57 % (P < 0.01). Conclusion: Fast spiral CT (RUSH-CT) significantly reduces the time needed for diagnostic work-up and allows early therapeutic intervention. CT diagnosis can be completed within the first 30 min after the patient's admission.

“…Providing functional and morphological information, CT is the most specific imaging method for detection and characterization of blunt renal trauma and plays an important role in patient management [90,91,92,93]. When examining trauma patients HCT has significant advantages over CCT, since fast volume scanning requires less patient cooperation and thus creates fewer artefacts [90,91,92,93].…”

Despite of the diagnostic potential of conventional CT (CCT), limitations being inherent in this technology reduce its diagnostic confidence and limit clinical CT applications as 3D imaging. Helical CT (HCT) has far overcome the limitations of CCT and has become the standard CT technology. After a short overview on the technique of HCT and its advantages over CCT, the impact of HCT on the detection of disorders of the urinary organs is discussed. Due to the high quality of 3D reconstructions, vessels are visualized free of artefacts resulting in a dramatic improvement and acceptance of CT angiography, which has become a clinically important examination in the evaluation of obstructive renal artery disease. Fast HCT provides a precise assessment of the three phases of the nephrogram and it is a prerequisite for an improved depiction of abnormal vascular perfusion and impaired tubule transit of contrast material. Helical CT enables an improved characterization of cystic mass lesions reducing the diagnosis of indeterminate masses and thus facilitating a better therapeutic management. The diagnosis of renal cell carcinomas (RCC) has improved due to an increased sensitivity in detecting small RCCs, and an increased specificity in the diagnosis of neoplastic lesions. Improved staging of RCCs is the result of accurate assessment of venous tumour extension. When planning nephron-sparing surgery 3D display of the renal tumour helps to determine the resectability of the mass depicting its relation to major renal vessels and the renal collecting system. In the evaluation of renal trauma HCT provides shorter scanning time and thus fewer artefacts in the examination of traumatized patients who cannot cooperate adequately. Three-dimensional postprocessing modalities allow the assessment of the renal vascular pedicel by CT angiography and improve the demonstration of complex lacerations of the renal parenchyma. In the evaluation of the upper urinary tract unenhanced HCT has become the imaging method of choice in the diagnosis and differential diagnosis of acute flank pain since it is highly sensitive and specific in detecting calculus disease. Unenhanced HCT may furthermore demonstrate causes of flank pain unrelated to urolithiasis. Gapless volume scanning and improved resolution in the z-axis during the excretory phase enables improved visualization of the renal collecting systems and ureters, resulting in a better demonstration of intraluminal and extraluminal pathology.
