Conditions

Among patients who visited the emergency department and underwent trunk CT examination, cases in which a prior trunk CT had previously been performed at our hospital and the past images were stored in the PACS.

Interventions

None listed

Eligibility

Sex/Gender

All

Inclusion criteria

Inclusion criteria: Patients who visited the emergency department of our hospital and underwent trunk CT imaging Cases in which prior trunk CT images obtained at our hospital were stored in the PACS and available for subtraction analysis Age over 18 years Slice thickness under 5.0 mm Field of view 200-800 mm tube voltage 70-140 kVp

Exclusion criteria

Exclusion criteria: Cases in which bone evaluation is markedly difficult due to metal implants or imaging artifacts Cases in which subtraction analysis is inappropriate because the imaging range or acquisition conditions differ substantially from those of prior images Cases in which the patient or their legal representative has expressed refusal to participate in the study

Design outcomes

Primary

Measure	Time frame
Evaluation of the impact of TSB use on the sensitivity and specificity for detecting fracture findings (including traumatic and pathological fractures), using specialist diagnosis as the gold standard.	—

Secondary

Measure	Time frame
Evaluation of the agreement between fracture diagnoses made by the study investigators and specialist diagnoses Evaluation of the fracture detection rate in the initial assessment by emergency department physicians and its agreement with specialist diagnoses Assessment of the impact of TSB on reader`s diagnostic confidence scores Comparison of the usefulness of TSB according to fracture site Evaluation of the presence or absence of bone metastases Additional usefulness of TSBV for detecting spinal canal changes associated with fractures Additional usefulness of TSB in differentiating traumatic fractures from pathological fractures Exploratory evaluation of the correlation between the quantitative range of color tone changes on TSB subtraction images and fracture findings	—
