Background: This Special Report summarizes the 2022, AAPM grand challenge on Truth-based CT image reconstruction.
Purpose: To provide an objective framework for evaluating CT reconstruction methods using virtual imaging resources consisting of a library of simulated CT projection images of a population of human models with various diseases.
Methods: Two hundred unique anthropomorphic, computational models were created with varied diseases consisting of 67 emphysema, 67 lung lesions, and 66 liver lesions.

BACKGROUND Emphysematous urinary tract infections are rare and serious conditions that are often multifactorial in etiology and may be associated with the presence of renal stones. Diagnosis can be made by finding gas within the renal collecting system or parenchyma. However, the radiographic finding of gas within a renal stone is rare and little has been published to describe the significance of this finding, its promoting factors, and management.

Emphysematous polycystic renal infection (EPRI) has a poor prognosis with conservative management, and early surgical nephrectomy has been recommended. However, percutaneous cyst drainage may be a possible treatment option. We experienced 6 patients with autosomal dominant polycystic kidney disease (ADPKD) presenting with EPRI.

Objective: To evaluate the relevance of established surgical risk calculators (SRCs) for predicting complications in patients undergoing percutaneous lung cryoablation (PLC).
Methods: The institution's database was queried for PLC procedures from March 2015 to May 2024, excluding those patients with concomitant local therapies or five or more lesions treated in a single setting. Demographics, frailty metrics as defined by the surgical literature, and procedural variables were collected.
