AI for Image Based Kidney Stone Detection
4
Feb

Overview

AI detects kidney stones on CT and characterizes size and density for management planning. Automated tools speed diagnosis in acute flank pain presentations. Quantitative metrics guide intervention decisions.

Techniques

Segmentation and classification models identify stones and measure dimensions and attenuation. Low dose CT protocols combined with AI maintain sensitivity. Integration with reporting systems streamlines care.

Clinical Impact

Rapid detection reduces time to analgesia and urologic consultation. Automated measurements support decisions on conservative versus interventional management. Follow up imaging tracks stone passage or growth.

Validation

Comparison with manual measurements and clinical outcomes validates utility. External validation across scanners and protocols ensures generalizability. Continuous monitoring maintains performance.

Whole Spine Lateral

Feb

Overview

Whole spine lateral radiographs evaluate sagittal alignment from cervical to sacral regions under physiologic load. They are used to assess global balance and plan corrective spinal surgery. Proper positioning ensures inclusion of all spinal segments.

Technique

Obtain a full length lateral radiograph with the patient standing and arms positioned to avoid obscuring the spine. Use consistent posture and include a calibration marker for measurements. Immobilize and instruct the patient to maintain natural stance.

Clinical Indications

Whole spine lateral views are indicated for deformity assessment adult spinal deformity and preoperative planning. They quantify sagittal vertical axis pelvic parameters and lumbar lordosis. Serial imaging monitors progression and postoperative outcomes.

Image Assessment

Measure sagittal vertical axis pelvic tilt pelvic incidence and lumbar lordosis. Assess for compensatory mechanisms and vertebral deformity. Report findings to guide surgical planning and alignment goals.
