CT scans are often used to find cancer, bone fractures, internal bleeding, blood clots, and injuries to the spine and brain. An MRI shows certain diseases that a CT scan can’t. For instance, uterine, prostate, and certainliver cancersare hard to see on a CT scan. Also, an MRI is u...
Patients were excluded from the study who were allergic to an iodine contrast, had an abnormal heart rate or could not take beta blockers. Patients who were admitted to the hospital were also excluded. “We looked to determine the length of stay and times between critical points in the treat...
cleaned and formatted retrospectively by ten radiologists with 3–20 years of experience (five radiologists at GR and five at KB). Data include demographic variables: age and sex, variables from the clinical examination include: body weight and height, body mass index, heart rate, body temperature...
the focus is not on the lungs, but on a person’s heart. A doctor might order a cardiac CT to detect problems with the aorta, heart valves and other arteries. In some cases, a doctor might order a cardiac CT scan to follow up on the results of a procedure, such as coronary artery...
In cardiac imaging, it is capturing the heart while moving, which therefore requires speed. The Naeotom Alpha delivers speed thanks to its Dual Source design and benefits from spectral information and high resolution for removing obstructions caused by calcifications. This enables diagnost...
A CT scan uses what’s called “ionizing” radiation. It’s powerful enough to pass through your body to create clear images on a computer. This type of radiation could raise your chances ofcancerat some point in the future. But it’s important to remember that ionizing radiation is around...
Furthermore, for organs which are affected by motion, a mismatch between the emission and the transmission scan will likely introduce errors into the attenuation-corrected SPECT scan. This is very frequently the case in organs like the heart, the lung, and the abdominal organs [39]. Often, ...
(1.5 L/min for induction, 0.6 L/min for maintenance) and monitored with a pulse oximeter and a heart-rate sensor during preparation and all acquisitions. A tail vein (22G) and an IP catheter (20G) were inserted for contrast injections. The IP injections were performed in the right lower...
Since the lungs are soft and fairly passive organs, they are influenced by respiration and heartbeat, resulting in discontinuity of lung motion and large deformation of anatomic features. This poses great challenges for accurate registration of lung image and its applications. The recent application ...
