A cVRT image shows a posterior view of the three renal arteries, two on the left and one on the right, without signs of stenosis. An accessory artery, originating off the aorta on the right, between the CA and the SMA, is seen, departing upwards to the left hepatic lobe.

Bilateral congenital hydronephrosis associated with hypertension in an infant

2025-05-14

A 5-month-old baby, suffering from severe hypertension, was presented to the hospital. Ultrasound examination showed bilateral congenital hydronephrosis. A contrast CT scan was performed with a dual source photon-counting detector CT, NAEOTOM Alpha.Pro, to rule out renovascular etiology of the hypertension prior to pyeloplasty.

Clinical Results
A cinematic VRT image rendered with UHR images acquired on PCD CT, shows retained contrast agent near the neck of the aneurysm. The curved segment of the flow diverter appears slender. The structures of the diverter are shown in detail without interference of artifacts caused by the struts.

Follow up on an unruptured intracranial aneurysm treated with a flow diverter

A 75-year-old female patient was presented to the hospital due to an episode of instability. A routine examination revealed a progressive conductive hearing loss on the right side. An ultra-high resolution scan was performed using a dual source photon-counting detector CT, NAEOTOM Alpha®, to investigate the etiology of her hearing loss.

Two corresponding curved MPR images, using standard and ZeeFree reconstruction, demonstrate a clear visualization of mild stenoses in the proximal LAD, caused by calcified plaques, after the ZeeFree correction. A non-calcified plaque in the mid LAD is also seen.

Multi-vessel coronary atherosclerosis – significant stenoses?

2024-10-16

A 78-year-old female diabetic patient, with clinical symptoms of a suspected stable angina, came to the hospital for a check-up. A coronary CT angiography was requested to evaluate the coronary arteries and to rule out coronary stenosis. A prospectively ECG-triggered sequential mode was performed with a dual source photon-counting detector CT, NAEOTOM Alpha®.

Macromastia with severe ptosis

2024-10-02
A 32-year-old female patient, suffering from bilateral symptomatic breast hypertrophy with severe ptosis, was scheduled for a reduction mammaplasty. CTA was performed, using a UHR scan mode with a dual source photon-counting detector CT, NAEOTOM Alpha®, to assess the dominant blood supply of the nipple-areola complex (NAC) and its vascular sources.
