“…In our study, the "experienced" reader had one year of relevant reading experience, and the "inexperienced" reader had no prior experience. Although our study cannot be directly compared with the Canella et al (14) study since our focus is completely different (pathological features of the knee rather than the hand), both studies reported excellent intrareader reliability. In a study by Xia et al (17), two "skilled" radiologists showed excellent inter-reader reliability (κ=0.91) for imaging assessment of subtle skeletal trauma (e.g., fractures of the bones in the limbs, nose, and pelvis) using tomosynthesis.…”

“…In the literature, its use has been reported for imaging of lungs (1−4), breast (5−7), and head and neck region (8−10); for visualization of kidneys through intravenous pyelogram (11); for localization of an endorectal balloon for prostate image-guided radiation therapy (12); and for evaluation of aortic arch calcification (13), and bone and joint pathologies (14−21). While its clinical use has become common in chest and breast imaging, its clinical application in arthritis imaging is scarcely documented in the literature (14,15,22).…”

“…Only three studies have reported reliability of tomosynthesis for assessment of skeletal pathology. Canella et al (14) reported the use of tomosynthesis for evaluation of bone erosions in hand rheumatoid arthritis. They reported excellent intrareader reliability (intraclass correlation coefficient [ICC]=0.99) for an expert reader (17 years of experience in radiologic assessment of arthritis) and equally excellent inter-reader reliability (ICC=0.96) among three readers (other two readers having three and eight years of experience).…”

ORIGINAL ARTICLE PURPOSE We aimed to assess reliability of the evaluation of osteophytes and subchondral cysts on tomosynthesis images when read by radiologists with different levels of expertise. MATERIALS AND METHODSForty subjects aged >40 years had both knees evaluated using tomosynthesis. Images were read by an "experienced" reader (musculoskeletal radiologist with prior experience) and an "inexperienced" reader (radiology resident with no prior experience). Readers graded osteophytes from 0 to 3 and noted the presence/absence of subchondral cysts in four locations of the tibiofemoral joint. Twenty knees were randomly selected and re-read. Inter-and intrareader reliabilities were calculated using overall exact percent agreement and weighted κ statistics. Diagnostic performance of the two readers was compared against magnetic resonance imaging readings by an expert reader (professor of musculoskeletal radiology). RESULTSThe experienced reader showed substantial intrareader reliability for graded reading of osteophytes (90%, κ=0.93), osteophyte detection (95%, κ=0.86) and cyst detection (95%, κ=0.83). The inexperienced reader showed perfect intrareader reliability for cyst detection (100%, κ=1.00) but intrareader reliability for graded reading (75%, κ=0.79) and detection (80%, κ=0.61) of osteophytes was lower than the experienced reader. Inter-reader reliability was 61% (κ=0.72) for graded osteophyte reading, 91% (κ=0.82) for osteophyte detection, and 88% (κ=0.66) for cyst detection. Diagnostic performance of the experienced reader was higher than the inexperienced reader regarding osteophyte detection (sensitivity range 0.74-0.95 vs. 0.54-0.75 for all locations) but diagnostic performance was similar for subchondral cysts. CONCLUSION Tomosynthesis offers excellent intrareader reliability regardless of the reader experience, but experience is important for detection of osteophytes.

“…It has also been used for evaluation of fracture healing [15], with similar results. In peripheral arthritis imaging, it has been shown to be better than radiography but not as good as CT [16] but almost as good as MRI in detecting erosions [17]. Digital linear tomosynthesis in musculoskeletal applications should not be seen as a tool to replace CT, but as an improvement on radiography to provide better imaging at low cost and low added dose.…”

“…Therefore, tomosynthesis can detect overlapping structures clearly, whereas it may be difficult to evaluate them by radiography [8,9]. For that reason, tomosynthesis is expected to detect more early RA bone lesions than does radiography.…”

Rheumatoid arthritis (RA) is a systemic disease that is caused by autoimmunity. RA causes synovial proliferation, which may result in bone erosion and joint space narrowing in the affected joint. Tomosynthesis is a promising modality which may detect early bone lesions such as small bone erosion and slight joint space narrowing.Nevertheless, so far, the optimal reconstruction filter for detection of early bone lesions of fingers on tomosynthesis has not yet been known. Our purpose in this study was to determine an optimal reconstruction filter setting by using a bone phantom. We obtained images of a cylindrical phantom with holes simulating bone erosions (diameters of 0.6, 0.8, 1.0, 1.2, and 1.4 mm) and joint spaces by aligning two phantoms (space widths from 0.5 mm to 5.0 mm with 0.5 mm intervals), examining 6 reconstruction filters by using tomosynthesis. We carried out an accuracy test of the bone erosion size and joint space width, done by one radiological technologist, and a test to assess the visibility of bone erosion, done by 5 radiological technologists. No statistically significant difference was observed in the measured bone erosion size and joint space width among all of the reconstruction filters. In the visibility assessment test, reconstruction filters of Thickness+-and Thickness--were among the best statistically in all characteristics except the signal to noise ratio. The Thickness+-and Thickness--reconstruction filter may be optimal for evaluation of RA bone lesions of small joints in tomosynthesis.
