2. Fig. 1
66 year old female presenting with hypogastric pain with bilateral costovertebral angle tenderness. Axial NCCT image (a) shows a calculus in left upper ureter. Axial image (b) at the level of pelvis and coronal (c) show colonic diverticulosis with diffuse bowel wall thickening, extensive pericolonic fat stranding and fluid in distal sigmoid colon, suggesting acute diverticulitis.

3. Fig. 2
79-year-old man with history of nephrolithiasis, undergoing follow-up ultrasound. Sagittal image of the left kidney reveals a large stone in the lower pole (arrow), with posterior acoustic shadowing (arrowheads).

4. Fig. 3
Axial (a) and coronal (b) non-contrast CT images from a patient presenting with left flank pain and gross hematuria. A large staghorn calculus (arrow) occupying the majority of the left renal collecting system was identified,with focal cortical scarring in the lower pole (arrowhead). Volumetric analysis allows to more accurately estimate stone burden in complex calculi than morphological measurements.

5. Fig. 4
Characterization of kidney stones using dual-energy computed tomography (DECT). Axial non-contrast CT image (a) shows a calculus at the upper-pole region of left kidney. Post-processed color map (b) shows a calcium containing calculus in the left kidney colored in blue. Dual energy plot (c) confirms the composition of the stone (arrow).

6. Fig. 5
Characterization of kidney stones using dual-energy computed tomography (DECT). Axial non-contrast CT image (a) shows a small calculus at the mid-pole region of the right kidney. Post-processed color map (b) showing a uric acid renal calculus in the right kidney colored in red. Dual energy plot (c) confirms the composition of the stone (arrow). Note the mild dilatation of right pelvicalyceal system (a), due to another calculus in the right ureter (not shown).

7. Fig. 6
52 year old woman with history of recurrent nephrolithiasis. Following a recent lithotripsy and stent placement, a follow-up CT was performed. Axial non-contrast CT (a) highlights the difficulty separating a residual calculus (arrow) from the ureteric stent (arrowhead). Color-coded dual-energy CT (b) exhibits the benefits of material decomposition, allowing the stone to be clearly delineated from the adjacent stent. An additional stone fragment (c, arrow) was also detected in the distal left ureter adjacent to the stent (arrowhead), best seen on dual-energy images.

8. Fig. 7
33 year old female with early pregnancy presented with recent onset left flank pain. Ultrasound image (a) shows pelvicalyceal system dilatation in the left kidney. Ultrasound images in transverse (b) and longitudinal (c) planes at the level of bladder show a small calculus at vesicoureteric junction and dilated lower ureter. A gravid uterus with gestational sac and a well defined fetal pole can also be noted (c & d).
