“…Tomosynthesis presented a constant sensitivity (68.5%), irrespective of the size of the lesion, with a superior increase for small tumors under 1 cm 3 (P = 0.0039), through a reduction in the phenomena of convergence [14]. This stable detection sensitivity, irrespective of lesion size, is also observed with MRI [45].…”

“…The number of scientific papers on DT has increased over the years (1, 3, 5, 7, 18-25), which is an indicator of increasing interest. DT is associated with a low radiation dose compared with OMU CT, and with improved detection compared with PNS radiography (1, 6, 18, 26-32). From our results using a standard anthropomorphic phantom, the effective dose for PNS DT is approximately 0.06 mSv by manufacturer's default and 0.026 mSv by our low dose modification, which is approximately 3 times higher than that used for radiographic examination (0.01 mSv); however, it is approximately 30 times lower than that used for OMU CT examination (0.91 mSv) (6, 24).…”

ObjectiveWe investigated low dose digital tomosynthesis (DT) for the evaluation of the paranasal sinus (PNS), and compared its diagnostic accuracy with a PNS radiography series (XR).Materials and MethodsWe enrolled 43 patients for whom XR, PNS DT, and OMU CT were performed. We measured effective doses (EDs) of XR, DT, and OMU CT using Monte Carlo simulation software. Two radiologists performed independent observation of both XR and DT. For seven PNSs, they scored anatomic conspicuity of sinuses and confidence on the presence of sinusitis using nine point scales. OMU CT was observed by the third radiologist and the findings were regarded as reference standard. We compared scores for conspicuity and sinusitis confidence between XR and DT.ResultsMean EDs were 29 ± 6 µSv, 48 ± 10 µSv, and 980 ± 250 µSv, respectively, for XR, DT, and CT. Mean scores for conspicuity were 6.3 and 7.4, respectively, for XR and DT. Sensitivity per patient basis for sinusitis detection were 52% and 96%, respectively, for XR and DT in observer 1 (p = 0.001) and 80% and 92% for observer 2 (p = 0.25). Specificities for sinusitis exclusion were 100% for both XR and DT for observer 1 and 89% and 100% for observer 2 (p = 0.50). Accuracies for sinusitis diagnosis were 72% and 98%, respectively, for XR and DT for observer 1 (p = 0.001) and 84% and 95% for observer 2 (p = 0.125).ConclusionPatient radiation dose from low dose DT is comparable with that of PNS XR. Diagnostic sensitivity of DT for sinusitis was superior to PNS XR.

“…Les petits amas de microcalcifi cations amorphes (très peu denses) peuvent être également diffi ciles à repérer. La tomosynthèse est d'un apport récent, elle est intéressante dans la mise en évidence de distorsions de petite taille [3]. L'échographie précise le caractère solide ou liquidien d'une masse ronde, et apporte des critères dans la diff érenciation bénin-malin d'une image mammographique ambiguë.…”
