1. Grayscale ultrasonographic image in CKD
Grayscale ultrasonographic image in CKD. (A) Grayscale longitudinal ultrasonographic image of a 67-year-old man with stage 4 CKD (creatinine, 4.0 mg/dl) and long-standing hypertension.
Grayscale ultrasonographic image in CKD. (A) Grayscale longitudinal ultrasonographic image of a 67-year-old man with stage 4 CKD (creatinine, 4.0 mg/dl) and long-standing hypertension. Kidney size is small (8.78 cm) and renal parenchyma is thin. The finding of small kidneys or a thin parenchyma is diagnostic of CKD. (B) Grayscale longitudinal ultrasonographic image of RK demonstrates kidney size of 11.4 cm, abnormal bright (diffusely increased echogenicity) renal parenchyma, although parenchymal thickness is normal, in a 32-year-old man with CKD (creatinine 3.3 mg/dl) due to severe poorly controlled hypertension (BP, 230/130 mmHg at time of examination).
