“…Most previous diagnostic comparison studies of tomosynthesis and CT such as those involving lung nodule findings or breast cancer diagnoses, investigated only the sensitivity or specificity of tomosynthesis and used CT as the gold standard. [15][16][17] The equivalence test was used in this study to confirm the validity of tomosynthesis. The equivalence test has been strongly recommended for demonstrating the comparability of treatment effects in various research fields, including medical studies.…”

“…In addition, in our study, the diagnostic accuracy of tomosynthesis was investigated using the methods of previous studies of lung nodule findings or breast cancer diagnosis. 16,21,22 The image condition and the timing of capture were not the same for both modalities according to a previous study that compared the usefulness of tomosynthesis and CT. 23 However, the present study compared CT and tomosynthesis performed on the same day. The data obtained using both modalities were reconstructed with slice thickness of 2 mm in the coronal and sagittal planes.…”

Purpose: To compare tomosynthesis and computed tomography (CT) for evaluating bone plug integration after anterior cruciate ligament (ACL) reconstruction with a boneepatellar tendonebone (BPTB) graft. Methods: Data of consecutive adult patients who underwent ACL reconstruction with BPTB were analyzed. Bone integration between the bone plug and bone tunnel was evaluated by tomosynthesis and CT, which were both performed 3 months postoperatively. The obtained data for both modalities were reconstructed with slice thickness of 2 mm. Evaluation of bone integration were separately performed using coronal-and sagittal-reconstructed images for the femur and tibia. The ratio of bone integration between the reconstructed slices in which bone grafting was involved, for both tomosynthesis and CT, was investigated by 2 blinded examiners. The equivalence of tomosynthesis to CT was tested by comparing the bone integration ratio for both modalities. The accuracy of diagnosing bone union using tomosynthesis and CT was also investigated. Results: The diagnostic accuracy of tomosynthesis and CT exceeded 80%. Interobserver agreement of bone integration in the sagittal plane on the femoral side was 0.92 (intraclass correlation coefficient) for CT and 0.76 (intraclass correlation coefficient) for tomosynthesis. Conclusions: Although it showed poor reliability, tomosynthesis was equivalent to CT in evaluating bone plug integration after ACL reconstruction with BPTB.

Lung cancer is the leading cause of cancer death and second most common cancer among both men and women, but most of them are detected when patients become symptomatic and in late-stage. Chest radiography (CR) is a basic technique for the investigation of lung cancer and has the benefit of convenience and low radiation dose, but detection of malignancy is often difficult. The introduction of computed tomography (CT) for screening has increased the proportion of lung cancer detected but with higher exposure dose and higher costs. Digital chest tomosynthesis (DCT), a tomographic technique, may offer an alternative to CT. DCT uses a conventional radiograph tube, a flat-panel detector, a computer-controlled tube mover and reconstruction algorithms to produce section images. It shows promise in the detection of potentially malignant lung nodules, with higher sensibility than CR, and is emerging as a low-dose and low-cost alternative to CT to improve treatment decisions. In fact, an increasing number of researchers are showing that tomosynthesis could have a role in the detection of lung cancer, in addition to its present role in breast screening. However, DCT offers some limitations, such as limited depth resolution, which may explain the difficulty in detecting pathologies in the subpleural region and the occurrence of artefacts from medical devices. Once solved these limitations and once more studies supporting its use will be available, DCT could become the first-line lung cancer screening tool among patients at considerable risk of lung cancer.

“…Aditionally, it alsohas several advantages over chest X-ray: 1) it improves lesion detection by reducing artifacts caused by overlapping anatomical structures; 2) it facilitates 3-dimensional localization; 3) it offers improved contrast resolution; and 4) it is more sensitive. 11 , 12 , 13 , 14 , 15 …”
