Computed Tomography News & Stories

Three-dimensional Cinematic Rendering images highlight the calcified plaques in the proximal LAD and RCA. Note that the images used for the rendering are reconstructed at 0.2 mm with a sharp kernel of Bv64.

A case of hemiparesis and dysarthria after stenting of the left internal carotid artery

 2024-04-23

A 64-year-old male patient, complaining of atypical chest discomfort during exercise and palpitations at rest, presented himself to the hospital. A coronary CT angiography was performed on a Dual Source photon-counting CT, NAEOTOM Alpha®, using a Quantum HD cardiac mode to rule out exercise-induced coronary insufficiency.

Clinical Results
MPR images show a small lung nodule centrally captured by an 18G biopsy needle.

Percutaneous lung biopsy of a small metastatic nodule under CT guidance

 2024-04-09

A 61-year-old male patient, suffering from a renal cell carcinoma (RCC), underwent a CT examination for staging. A small lung nodule was detected, suspicious of a metastasis. The patient was admitted for a biopsy of the lesion under CT guidance.

Extensive coronary calcifications with high-risk plaques

 2024-03-26

A 64-year-old male patient, complaining of atypical chest discomfort during exercise and palpitations at rest, presented himself to the hospital. A coronary CT angiography was performed on a Dual Source photon-counting CT, NAEOTOM Alpha®, using a Quantum HD cardiac mode to rule out exercise-induced coronary insufficiency.

Clinical Results
A cVRT image shows a three-dimensional overview (7 lesions in green) and a clip from the cholecystectomy.

Multiple gastrinomas

 2024-01-26
A 37-year-old female patient, complaining of chronic epigastric pain, had had a cholecystectomy as treatment but the pain persisted. She was referred to CT to investigate a suspected Zollinger Ellison Syndrome. A multiphase dynamic CT scanning of the upper abdomen was performed, with thin slice reconstruction to capture all potential lesions.
Clinical Results
A UHR image, an iodine map and a thin slab cVRT image show a prominent nerve root sleeve and a CVF.

Cerebrospinal fluid-venous fistula detected in a patient with a long history of headaches

 2024-01-12

A 58-year-old female patient with a 10-year history of migraine, tinnitus and orthostatic headache, was diagnosed of spontaneous intracranial hypotension. CT myelography was performed on a photon-counting CT, NAEOTOM Alpha®, using a UHR scan mode to identify and localize the suspected cerebrospinal fluid-venous fistula prior to a definitive treatment.
