“…In this study, we found that the two-image set created using the software that automatically flattens the ribs on a single image plane helped novice readers to evaluate the chest CT examinations faster than the standard method. Our findings are in concordance with the ones that Ha et al reported in their paper, in which they evaluated the effect of rib-flattening software on a radiologist's performance [8]. They stated that this specific software helped to improve radiologists' performance, especially for the inexperienced reader.…”

“…They demonstrated that the use of a new algorithm for curved planar images providing flattened-rib images eases the evaluation and increases accuracy [7]. Other authors found that unfolded curved planar images may reduce reading times and increase accuracy in the detection of rib lesions in prostate cancer, breast cancer, and multiple myeloma patients [8][9][10]. However, there are some drawbacks to the abovementioned technique: the time required to launch the application distracts the attention of the reader, and a necessity for multiple licenses increases the cost for the radiology department.…”

Evaluation of a two-image technic consisting of an axial and a coronal image generated by using the rib-flattening application: effect on reading time and diagnostic validity

Background/aim: When reading a chest CT, a radiologist needs to evaluate each rib one by one due to complex curvy shape, which makes reporting a tiresome and time-consuming task. A new curved planar reformat application that flattens ribs on a single plane may find a place in the radiology reporting room. This study aimed to evaluate the effect of a two-image set created by using the rib-flattening application on the performance of a radiologist in detecting sclerotic rib lesions in cancer patients. Materials and methods:The local Institutional Review Board approved this retrospective study. Two radiologists with different experience levels reviewed chest CT examinations of 106 patients (76 men, 30 women). We divided the patients into group A (n = 54), reviewed by a standard method, and group B (n = 52), reviewed by a standard method and the two-image set created on the ribflattening application. Reading times, validity indices, and agreement levels with reference data were evaluated for both readers. Results:The median reading time of the junior examiner significantly decreased with the rib-flattening method (160.5 s vs. 70.0 s; P < 0.001). Diagnostic indices of the senior reader were improved significantly at per patient level (group A, AUC: 0.867; group B, AUC: 0.982; P = 0.046). The new method showed better agreement levels (kappa: 0.69 to 0.96) than the general method (kappa: 0.53 to 0.91). Conclusion:Based on improved agreement levels, reading times, and diagnostic validity indices we conclude that a two-image set consisting of an axial and a coronal flattened-rib image may be used in conjunction with an ordinary exam.

“…8 Ha et al demonstrated that, in patients with breast cancer, the use of Bone Reading application improved radiologist performance in bone metastasis detection compared with conventional chest CT reading with reduced reading time. 13 Seuss et al reported that in-plane reading of the ribs provides reliable detection of osteoblastic lesions in the screening of prostate cancer patients. 3 In addition, in a study in which the effectiveness of skull unfold application was evaluated in the detection of intracranial hematoma, it was recommended to use the skull opening method in addition to reading transverse sections in routine clinical practice in patients with suspected of traumatic brain injury.…”

“…These findings are in line with findings of the other studies using different bone unfolding softwares. [12][13][14][15][16] On the other hand, in this era contributions of artificial intelligence to the performance of radiologists are extensively investigated and the unfolding software also might be able to be utilized for artificial intelligence interpretation. This is an avenue for future exploration.…”

Purpose: To evaluate the contribution of CT Bone Unfolding software to the diagnostic accuracy and efficiency for the detection of osteoblastic pelvic bone lesions in patients with prostate cancer. Methods: A total of 102 consecutive (January 2016-September 2019) patients who underwent abdominopelvic CT with prostate cancer were retrospectively evaluated for osteoblastic pelvic bone lesions, using commercially available the post-processing-pelvic bone flattening-image software package “CT Bone Unfolding.” Two radiologists with 3 and 15 years of experience in abdominal radiology evaluated CT image data sets independently in 2 separate reading sessions. At the first session, only MPR images and at the second session MPR images and additionally unfolded reconstructions were assessed. Reading time for each patient was noted. A radiologist with 25 years of experience, established the standard of reference. Results: In the evaluations performed with the MPR-Unfold method, the diagnostic accuracy were found to be 2.067 times higher compared to the MPRs method ( P < 0.001). The location of the lesions or the reader variabilities did not show any influence on accuracy ( P > 0.05) For all readers the reading time for MPR was significantly longer than for MPR-Unfold ( P < 0.05). For both methods substantial to almost-perfect inter-reader agreement was found (0.686-0.936). Conclusions: The use of unfolded pelvic bone reconstructions increases diagnostic accuracy while decreasing the reading times in the evaluation of pelvic bone lesions. Therefore, our findings suggest that utilizing unfolded reconstructions in addition to MPR images may be preferable in patients with prostate cancer for the screening of osteoblastic pelvic bone lesions.
