Abstract
Introduction:Manipulation of images using three-dimensional multiplanar reconstruction algorithms (3D MPR) and maximum intensity projection (MIP) is dependent on prior understanding of the method's true validity and its superiority over traditional semi-digital or analog methods of measurement.Objective:To assess the understanding of doctors who attended the course of the methodology they routinely employed for planning endovascular surgery before taking the course and determine their choice of method after completion of the course.Methods:A survey was conducted with the students who took the course using an intranet questionnaire.Results:One hundred and sixty-one participants responded to the questionnaire. In relation to their prior knowledge, 38.8% reported no knowledge, 45.6% reported little knowledge, 15% reported basic knowledge and just 0.6% considered their prior knowledge was advanced. With respect to the measurement method used, 12.5% relied on the measurements in the radiologist's report, 14% used printed plates and manual compasses, 36.8% used axial images to take measurements, 11.8% used axial images in OsiriX, 14% used the 3D MPR method and 11% used the 3D MPR method and 3D MPR combined with MIP. Additionally, 81.5% of the participants stated that they repeated measurements intraoperatively using a centimeter pigtail catheter, despite having taken measurements in advance using one of the methods listed above.Conclusion:The study showed that continuing education in specialized course was effective for imparting understanding of the importance of the three-dimensional multiplanar reconstruction image analysis method and of image optimization algorithms.

Manipulation of images using three-dimensional multiplanar reconstruction algorithms (3D MPR) and maximum intensity projection (MIP) is dependent on prior understanding of the method’s true validity and its superiority over traditional semi-digital or analog methods of measurement
We have left the analog era of medical image analysis behind,[1] adaptation to the new digital methods does demand dedication to the technique, and a good three-dimensional understanding of patient anatomy
An Apple computer is required to run the OsiriX software and the results showed that 92 (57.5%) of the participants already had one
Summary
Manipulation of images using three-dimensional multiplanar reconstruction algorithms (3D MPR) and maximum intensity projection (MIP) is dependent on prior understanding of the method’s true validity and its superiority over traditional semi-digital or analog methods of measurement. Manipulation of images employing algorithms for three-dimensional multiplanar reconstruction (3D MPR) and maximum intensity projection (MIP) are primarily dependent on an understanding of the method’s true validity and superiority over traditional analog or semi-digital measurement methods. This understanding is often acquired in an introductory course on manipulation of medical images using OsiriX software.[2,3]. This study was conducted with the physicians who took the course with the objective of assessing their understanding of the methodology they had been using for planning endovascular procedures prior to attending the course and to document their preferred method after completing the course.[4]
