Brief Summary:
The purpose of this study is to determine if Model-based iterative reconstruction MB-IR VEOTM in ultra low-dose abdominal CT as the same accuracy for the diagnosis of acute renal colic versus standard CT with adaptative statistical iterative reconstruction ASIR
Detailed Description:
Renal colic is a common recurrent pathology in young patients multi explored by imaging such as CT and abdominal radiography
Abdominal MDCTMultiDetector Computed Tomography without injection is the gold standard in diagnosis of acute flank pain suspect of renal colic due to high sensitivity 96 and excellent specificity 100
The increased use of medical imaging examinations using ionizing radiation 57 between 2002 and 2007 makes it essential to optimize protocols including CT-scans which represents 101 of procedures and 58 of the collective effective dose
Model-based iterative reconstruction MB-IR VEOTM GE Healthcare Milwaukee WI can use a low dose acquisition reducing the effective dose delivered to the patient almost 80 comparing a standard CT with the last algorithm adaptative statistical iterative reconstruction ASIR
MB-IR VEOTM shows great potential for substantially reducing radiation doses at routine abdominal CT ASIR is limited in this regard owing to reduced image quality and diagnostic capability Further investigation is needed to determine the optimal dose level for MBIRModel Base Iterative Reconstruction that maintains adequate diagnostic performance In general objective and subjective image quality measurements do not necessarily correlate with diagnostic performance at ultralow-dose CT
Objective
Prospective clinical study equivalence between two CT protocols for the diagnosis of acute renal colic
Show that a low dose acquisition with model based iterative reconstruction MB-IR VeoTM is as good as a standard CT with adaptative statistical iterative reconstruction ASIR in the diagnosis acute renal colic
