Table 2: Imaging techniques.

ADPKD diagnosisUltrasonography (US)Easy, available, and cheap method
Limited utility for disease exclusion in younger subjects and suboptimal performance for individuals with ADPKD type II
Computed tomography (CT) scanDetect small cysts (~2 mm)
Exposure to radiation and administration of intravenous contrast media
Magnetic resonance imaging (MRI)Provide high-resolution 3D images
No exposure to radiation, no administration of intravenous contrast media

Diagnosis of cardiovascular complicationsEchocardiographyDetermine LV/RV size and function, LV wall motion abnormalities, valvular function and abnormalities, diastolic function, and presence or absence of pericardial abnormalities or intracardiac masses
Transmitral pulsed dopplerNoninvasive method to evaluate the diastolic dysfunction
Influenced the loading condition of the left atria and heart rate.
Tissue doppler imaging (TDI)Permit an assessment of myocardial motion, a sensitive index of ventricular relaxation
Cardiovascular magnetic resonance imaging (cMRI)Noninvasive test
Gold standard for the assessment of ventricular dimensions.
