Summary of opportunities for artificial intelligence (AI) technology in oncological imaging.
| Current clinical practice | Potential for AI technology | |
|---|---|---|
| Screening/detection | Predominantly manual detection | May use automated or semi-automatic techniques to increase accuracy or efficiency |
| Diagnosis and risk stratification | Predominantly clinical “rules” based (TI-RADS, Lung-RADS, PI-RADS, etc.) | May improve accuracy |
| Tumour segmentation | Not typically done as it is highly labour intensive | May improve efficiency and reliability May allow for feature extraction for other uses of AI in oncological imaging |
| Precision oncology | Not typically done | May subtype tumours into known or new histopathology or genomic subtypes that can be targeted for therapy |
| Predicting prognosis and assessing treatment response | Tumours stage based on anatomy (local invasion and metastases) Treatment response typically size-based criteria (e.g., RECIST), limited by pseudoprogression or pseudoresponse |
May subtype tumours by tumour biology/grade to determine appropriate treatment May use other features in addition to tumour size including tumour morphology to determine response and to distinguish from treatment effects |
