“…Unlike previous studies of SOS (2,3), the imaging modalities presenting the added and test fractures were different. This opens the possibility that CT eliminated SOS because SOS effects do not extend from one imaging modality to another.…”

“…For the first experiment using minor added fractures, the 70 added fractures were presented on digital radiographs of the foot [6], ankle [4], tibia/fibula [7], knee [5], pelvis [3], chest [3], shoulder [10], arm [5], elbow [4], wrist [11], and hand/fingers [12]. The digital radiographs that were used in place of these examinations for the non-SOS condition had the same distribution of body parts.…”

“…Whether the test fracture appeared in the second or third examination was random, but the same order was used for both experimental conditions in all experiments. The 47 test fractures were presented on digital radiographs of the foot [15], ankle [4], tibia/fibula [2], knee [3], shoulder [4], arm [3], elbow [1], wrist [3], and hand/fingers [8]. The 97 normal examinations appearing in the second or third positions of the series (47 with the test fractures, and 54 as pairs to make 27 normal patients) were presented on digital radiographs of the foot [7], ankle [13], tibia/fibula [3], knee [20], pelvis [19], chest [15], shoulder [3], arm [3], elbow [5], wrist [2], and hand/fingers [7].…”

“…In 2001, gaze time on fractures was measured in an attempt to determine whether test fractures were missed in this SOS effect because of misdirection of attention (3). Although readers spent somewhat less time inspecting subsequent radiographs of a patient's trauma series after viewing initial radiographs that contained added fractures, they generally did look at the test fractures that they failed to report.…”

Satisfaction of Search in Multitrauma Patients: Severity of Detected Fractures

Purpose-Satisfaction of search (SOS) occurs when an abnormality is missed because another abnormality has been detected. This research studied whether the severity of a detected fracture determines whether subsequent fractures are overlooked.Materials and Methods-Each of seventy simulated multi-trauma patients presented examinations of three anatomic areas. Readers evaluated each patient under two experimental conditions: when the images of the first anatomic area included a fracture (the SOS condition), and when it did not (the control condition). The SOS effect was measured on detection accuracy for subtle test fractures presented on examinations of the second and third anatomic areas. In an experiment with twelve radiology readers, the initial SOS radiographs showed non-displaced fractures of extremities, fractures associated with low morbidity. In another experiment with twelve different radiology readers, the initial examination, usually a CT, showed cervical and pelvic fractures of the type associated with high morbidity. Because of their more direct role in patient care, the experiment using high morbidity SOS fractures was repeated with seventeen orthopedic readers.Results-Detection of subtle test fractures was substantially reduced when fractures of low morbidity were added (p<0.01). No similar SOS effect was observed in either experiment in which added fractures were associated with high morbidity. Conclusion-The satisfaction of search effect in skeletal radiology was replicated, essentially doubling the evidence for SOS in musculoskeletal radiology, and providing an essential contrast to the absence of SOS from high morbidity fractures.

“…An important way to achieve this is by examining how radiologists actually go about the interpretation of images by conducting eye tracking studies. Past studies that have used eye tracking to analyze conventional radiography have covered extensive research topics, such as radiologists' reading strategy, [1][2][3][4][5][6] perceptual and cognitive processes during the interpretative process, [7][8][9][10][11][12][13][14] differences in gaze patterns of experts and novices and how expert visual search could be trained, [15][16][17][18][19] display properties that are associated with superior performance, [20][21][22] the comparison of visual processes when satisfaction of search occurred, 23,24 gaze characteristics that are linked to different decision outcomes 25,26 and how these could be used to provide perceptually based feedback, [27][28][29][30][31][32][33][34] or how lesion properties influence radiologists' perception and decision making processes. [35][36][37][38][39] A number of studies have even looked at how eye tracking studies need to be conducted to yield the most valid results.…”

Abstract. While eye tracking research in conventional radiography has flourished over the past decades, the number of eye tracking studies that looked at multislice images lags behind. A possible reason for the lack of studies in this area might be that the eye tracking methodology used in the context of conventional radiography cannot be applied one-on-one to volumetric imaging material. Challenges associated with eye tracking in volumetric imaging are particularly associated with the selection of stimulus material, the detection of events in the eye tracking data, the calculation of meaningful eye tracking parameters, and the reporting of abnormalities. However, all of these challenges can be addressed in the design of the experiment. If this is done, eye tracking studies using volumetric imaging material offer almost unlimited opportunity for perception research and are highly relevant as the number of volumetric images that are acquired and interpreted is rising.

Communicating traumatic pathology to ensure shared understanding: is there a recipe for the perfect preliminary image evaluation?

Medical imaging and emergency departments work collaboratively to interpret trauma radiographs. In addition to accurate radiographic interpretation, clear communication is crucial to ensure appropriate and timely management of musculoskeletal injuries. This two-step 'how to guide' provides the reviewer with a recipe for effectively evaluating trauma radiographs for traumatic pathology and succinctly documenting the findings.Step 1 is a systematic search of the radiograph: soft tissues, bones, alignment of joints and satisfaction of search (SBASS). Utilising SBASS increases reviewer confidence in identifying traumatic pathology of the appendicular and axial skeleton.Step 2 is a streamlined communication model for the documentation of pathological findings. The WWW acronym (What is it? Where is it? What is it doing?) can be adapted to describe simple or complex traumatic pathology.
