- "The technique is also valuable in providing a time-efficient method to review pertinent findings with clinicians."
Evaluation of Periampullary Pathology With CT Volumetric Oblique Coronal Reformations
Pham DT et al.
DOI:10.2214/AJR.08.2069 - "Volumetric oblique coronal reformations are a useful noninvasive method to provide diagnostic information about periampullary abnormalities as well as show secondary features important for local staging and management. The technique is also valuable in providing a time-efficient method to review pertinent findings with clinicians."
Evaluation of Periampullary Pathology With CT Volumetric Oblique Coronal Reformations
Pham DT et al.
DOI:10.2214/AJR.08.2069 - "Multidetector CT with MPR allows improved visualization of the normal anatomy and anatomic variants as well as greater diagnostic accuracy in the evaluation of the female pelvis."
Added Value of Multiplanar Reformation in the Multidetector CT Evaluation of the Female Pelvis: A Pictorial Review
Yitta S et al.
RadioGraphics 2009; 29:1987-2005 - "Interpretation time with MPR was significantly longer for two of the three specialists and significantly shorter for two of the three residents."
Clinical Utility of Multiplanar Reformation in Pulmonary CT Angiography
Espinosa LA et al.
AJR 2010; 194:70-75 - "Use of MPR for viewing increased the reader agreement and interpretation time of cardiothoracic specialists but increased reader agreement between residents and might have decreased interpretation time. All readers had a trend toward increased confidence."
Clinical Utility of Multiplanar Reformation in Pulmonary CT Angiography
Espinosa LA et al.
AJR 2010; 194:70-75 - "If workstation and network constraints limit a departments capacity to manage 2x1 mm sections, the study results indicate that the thinnest feasible sections (e.g.3x3 mm rather than 5x5 mm) should be used for the best possible interpretive confidence."
MDCT for Suspected Appendicitis: Effect of reconstruction Section Thickness on Diagnostic Accuracy, Rate of Appendiceal Visualization, and Reader Confidence using Axial Images
Johnson PT, Horton KM, Kawamoto S et al.
AJR 2009; 192:893-901 - "Correctness of diagnosis was not significantly associated with reconstruction method. However, for correctly diagnosed cases as normal, impression confidence increased with progressively thinner section thickness (p<0.001 for 5x5 vs 3x3 and 3x3 vs 2x10)."
MDCT for Suspected Appendicitis: Effect of reconstruction Section Thickness on Diagnostic Accuracy, Rate of Appendiceal Visualization, and Reader Confidence using Axial Images
Johnson PT, Horton KM, Kawamoto S et al.
AJR 2009; 192:893-901 - "On the basis of our findings, we suggest that if multidetector CT is available, positive oral contrast material should not be a routine requirement for follow-up abdominal pelvic scans in oncology patients."
