Vascular Trauma
Published in James Michael Forsyth, How to Be a Safe Consultant Vascular Surgeon from Day One, 2023
In my particular unit, however, I would have to honest about what I think I would do in regards to asking for X-rays. My A&E department is literally right next door to the CT scanner, and I know it would be much quicker to get the patient a full body CT scan than it would to get X-rays of the chest/abdomen/pelvis. I also know that a CT scan starts off with a scout X-ray of the chest/abdomen/pelvis …. as such for pragmatic purposes if this patient were “stable” I would get an urgent CT scan (neck/chest/abdomen/pelvis, and I would also ask for the left arm to be included as a CT angio).
Multiple Myeloma
Published in Pat Price, Karol Sikora, Treatment of Cancer, 2020
All guidelines strongly recommend using cross-sectional imaging (low-dose full-body CT scan, PET-CT, plain whole-body MRI, diffusion-weighted MRI) for patients with myeloma rather than using plain imaging (skeletal survey).16 The presence of lytic bone lesions is a major diagnostic criterion for diagnosis.

Kamola described the terrible pain in her mother’s belly and Dr. Mishra’s face grew very serious. She wanted to know the name of the physician who saw her mother, prescribed MRI and a full body CT scan and biopsy of the lump for Kamola and asked her to bring her father to the hospital as soon as she got the reports of those examinations. She explained to her patient in very simple language what she needed to do next.
Paraconduit hernia after minimally invasive esophagectomy – incidence and risk factors

Esophageal cancer patients undergo a full body CT scan before the start of neoadjuvant therapy, after completion of neoadjuvant therapy and at 6 months after surgery. These scans were used to measure muscle mass and define sarcopenia before neoadjuvant treatments, before surgery and at 6 months of follow-up respectively. Scans were coded in order to blind the researchers from outcome. Images were imported to Osirix® Version 12.0 (32-bit Pixmeo, Sarl, Bernex, Switzerland). Abdominal musculature was delineated by use of a semi-automatic selection of region of interest tool from the level of L3. Psoas, quadratus lumborum, paraspinal, transverse abdominal, external oblique, internal oblique and rectus abdominis muscles were included. The Hounsfield Unit threshold range for skeletal muscle was −29 to +150. The images were manually corrected, if needed, by the propulsion and brush tools in Osirix©. Sarcopenia is defined as the progressive loss of muscle related to aging or disease [22]. The cross-sectional total muscle area at the level of L3, skeletal muscle area (SMA; unit: cm2) was divided by the square of height (m2), which produced the skeletal muscle index (SMI). This method is suggested as the preferred method of measuring the muscle mass of cancer patients [23]. SMI limit for sarcopenia was <52.4 cm2/m2 for men and <38.5 cm2/m2 for women, based on a previous study by Prado et al. [24].

Even though CPR-related injuries are significantly more common after mechanical reanimation devices, overall mortality did not significantly differ between the groups. This is mainly due to the differences mentioned above in low-flow time and prognostic factors, such as initial heart rhythm. Besides the occurrence of injuries, it seems vital to detect and treat these arrhythmias accordingly. A routine full-body CT scan directly after hemodynamic stabilization by eCPR followed by cardiac revascularization (if necessary) might be the most crucial step in diagnostics for these patients. In a full-body CT-scan study of 103 eCPR patients, 6.5 pathological findings could be demonstrated on average in each patient, namely rib fractures and pneumo- or hemothorax [9]. In our study, 55% of patients with cCPR before ECMO cannulation and 83% of patients after mCPR showed relevant injuries; these numbers may even be underestimated as not all patients received full-body imaging directly after eCPR. In summary, clinicians should perform an extensive search for injuries and hemorrhagic complications after eCPR.
Influence of material properties and boundary conditions on patient-specific models

Nine datasets were collected with images in the DICOM format hosted on the SICAS Medical Image Repository and provided by the SMIR team (Kistler et al. 2013). Each dataset contains a post-mortem full-body CT scan acquisition (Siemens Somatom Emotion 6, 130 KVp, 125 mAs, 0.9512 × 0.9512 × 0.6 mm3 voxel size). The corresponding acquisition method used a normalized, reproducible protocol aimed at limiting potential biases. The human subjects were selected as representative of the population; thus, our sampled population consisted of 6 men and 3 women aged between 22 and 90 years old (mean: 64.2). Only the left tibia was considered in this study.
