“…These images are supplementary to the primary CT angiography (CTA) images and are helpful for surgical planning [2,16]. Cinematic rendering (CR), a relatively new 3D technique which allows realistic shadowing effects which enable clear representation of the relative positions of objects within the imaged volume, is also being increasingly used for aortic presurgical planning and differentiating pathologies from normal variants [17,18]. As compared to VR, CR has improved ability to visualize the spatial relations (particularly in the through-plane) [18].…”

Imaging of the aortic root on high-pitch non-gated and ECG-gated CT: awareness is the key!

The aortic pathologies are well recognized on imaging. However, conventionally cardiac and proximal aortic abnormalities were only seen on dedicated cardiac or aortic studies due to need for ECG gating. Advances in CT technology have allowed motionless imaging of the chest and abdomen, leading to an increased visualization of cardiac and aortic root diseases on non-ECG-gated imaging. The advances are mostly driven by high pitch due to faster gantry rotation and table speed. The high-pitch scans are being increasingly used for variety of clinical indications because the images are free of motion artifact (both breathing and pulsation) as well as decreased radiation dose. Recognition of aortic root pathologies may be challenging due to lack of familiarity of radiologists with disease spectrum and their imaging appearance. It is important to recognize some of these conditions as early diagnosis and intervention is key to improving prognosis. We present a comprehensive review of proximal aortic anatomy, pathologies commonly seen at the aortic root, and their imaging appearances to familiarize radiologists with the diseases of this location.

“…In the OMD cohort, the primary tumor was most often located in the head of the pancreas or the uncinate process (n = 80, 69%), and the median size was 34 mm (IQR, [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43]. An association between the site of the primary tumor and location of OMD was not established.…”

Background The incidence of occult metastatic disease (OMD) in pancreatic ductal adenocarcinoma (PDAC) and associated risk factors are largely unknown. Methods We identified all patients with PDAC, who had an aborted oncologic operation due to OMD within a 10‐year period. The cases were matched to a cohort of resected PDAC patients on a 1:3 ratio, based on age and sex, for comparison of preoperative clinical characteristics and potential risk factors for OMD. Results In the studied period, 117 patients with OMD were identified in 1423 pancreatectomies performed for PDAC (8%). Liver metastases were the most common finding (79%) followed by peritoneal implants (16%). When compared with non‐OMD cases, patients with OMD presented more often with abdominal pain (P < 0.001), and higher preoperative carbohydrate antigen 19‐9 (CA 19‐9) values ( P = 0.007). Additionally, indeterminate liver lesions on preoperative computed tomography (CT) were identified in 40% of OMD versus 17% of non‐OMD patients ( P < 0.001). Multivariable analysis distinguished four independent predictors for OMD: indeterminate lesions on preoperative CT, tumor size > 30 mm, abdominal pain, and preoperative CA 19‐9 > 192 U/mL. Conclusions Occurrence of OMD in PDAC accounts for 8% of cases. Preoperative CA 19‐9 > 192 U/mL, primary tumor size > 30 mm, and identification of indeterminate lesions in preoperative CT may indicate the need for diagnostic laparoscopy.

“…Traditionally, VR relies on the principle of “ray casting,” in which a single line is traced from the viewer's screen through the voxels, simulating the trajectory of a beam of light 17 . In essence, ray casting simulates the emitted and absorbed energy of a single photon, summing the effects of a line of voxels 18 . The effect is a “one photon per pixel” approximation.…”

Three‐Dimensional Cinematic Rendering to Optimize Visualization of Cerebrovascular Anatomy and Disease in CT Angiography

Three-dimensional cinematic rendering (3DCR) is an emerging postprocessing technique for computed tomography (CT) and CT angiography (CTA) that produces photorealistic, volumetric images. In contrast to conventional volume rendering techniques, 3DCR depicts life-like shadowing and surface reflection, which can improve the perception of depth and complex anatomic spatial relationships. This tool allows clinical neuroimagers to study, explore, and teach the complex relational anatomy of the cerebral vessels and skull in a more intuitive manner. The purpose of this report is to introduce the physical and optical principles behind 3DCR and to explore applications of 3DCR in modern cerebrovascular imaging. Using CTA source data, we describe our approach to visualizing cerebrovascular anatomy and disease and introduce three simple, reproducible techniques through a series of case vignettes. First, we show how selective manipulation of rendered models can imitate cadaveric dissection. Next, we discuss surface rendering as a means of recapitulating the neurologic physical exam. Last, we provide a step-by-step method of simulating the operating room perspective in visualizing cerebrovascular disease. In our experience, 3DCR proves most useful for visualizing structures at the vessel-skull interface, which can be difficult to assess with conventional imaging methods. 3DCR, therefore, complements traditional 2-dimensional and 3-dimensional imaging methods and serves as an emerging tool for neuroimagers to communicate with and educate other clinicians.
