CT Imaging Protocol for Assessing HCC Response

Check if the same lab product or an alternative is used in the 5 most similar protocols

Chest, abdomen, and pelvis CT scans were performed with a 64‐section multidetector CT scanner (LightSpeed VCT or Optima CT660 or Revolution GSI; GE Healthcare, Milwaukee, WI, USA, http://www.gehealthcare.com). First, a precontrast abdominal scan was performed. Next, 300 mgI/mL of a nonionic iodinated contrast agent was administered intravenously. Its volume was 750 mgI/kg, and it was administered through a 20–22‐gauge catheter via an antecubital vein over 35 s. The arterial, portal venous, and equilibrium phases were obtained 40, 70, and 150 s after contrast medium administration, respectively. No oral contrast medium was administered.
For each target lesion, arterial phase acquisition was used to measure the maximum diameter, the maximum unidimensional enhanced diameter, the product of the bidimensional enhanced diameters, and tumor density. Based on these parameters, we evaluated the response according to the RECIST 1.1, mRECIST, and Choi criteria, as previously reported.¹⁴ Due to the absence of specific guidelines on the use of the Choi criteria in HCC, we adapted the original Choi criteria to fit specific HCC patterns, as previously reported.²⁶ Because HCC is a hypervascular tumor, the density was measured during the arterial phase instead of the portal phase, as originally described for GISTs.²⁵, ²⁶, ²⁷

The Institutional Review Board approved this Health Insurance Portability and Accountability Act-compliant single-center retrospective study; the requirement for informed consent was waived. A total of 100 consecutive patients who had history of primary or secondary liver cancer were included in this study. Each patient underwent multiphasic liver CT exams between June 2015 and December 2015. All patients were scanned with a single source, rsDECT scanner (Revolution GSI, GE Healthcare, Milwaukee, WI). Two patients were excluded because of excessive motion artifacts. The final study population was 98 patients, 63 (64%) were men. The average age of all patients was 60 years (range, 16–87). Radiation dose analysis was performed in a subset of 44 patients who had also undergone a multiphasic SECT examination (Discovery CT750 HD, GE Healthcare, Milwaukee, WI, USA) within 6 months of the rsDECT (mean age 61.4 years; range, 32–82).

Tube Current Modulation in CT Imaging

Check if the same lab product or an alternative is used in the 5 most similar protocols

Acquisitions were performed on a 64-detector row CT scanner (Revolution GSI, GE Medical Systems). This scanner is equipped with OTCM (ODM, GE Medical Systems). OTCM constitutes a tube current modulation mode that reduces the mA when the tube travels across the anterior arch of the patient’s circumference without increasing it over the remaining lateral and posterior arches. To enable OTCM, the AutomAtic tube current modulation (ATCM) system (AutomA and SmartmA, GE Medical Systems) needs also to be activated. In head, the mA is reduced by up to 30% across 90° anterior projections, while in body, the mA is reduced by up to 40% across 180° anterior projections (Fig. 1) [18 ].Fig. 1

A graphical illustration of the configuration setup used in the MC simulation experiments showing the positioning of the phantom with regard to the angle of OTCM mA reduction. For head, the mA was reduced by 30% in 9 out of 36 tube positions, while for body, the mA was reduced by 40% in 18 out of 36 tube positions

Cranial CT Imaging Protocol for mTBI

Check if the same lab product or an alternative is used in the 5 most similar protocols

An emergency cranial CT scan was performed using a GE Healthcare Revolution GSI® according to the following protocol: helical mode with a slice thickness of 2.25 mm, an interval of 1.25 mm, 120 kV, and a maximum of 280 mA from C1 to the top of the head with additional bone window reconstructions. All CT scans were analyzed by a radiologist. To determine whether patients had a trauma-relevant intracranial lesion, radiological parameters were recorded. The patients were divided into two groups: normal CT scan (CT–) for mTBI patients with no signs of trauma-relevant intracranial lesions and abnormal CT scan (CT+) for mTBI patients with at least one pathophysiological trauma-relevant intracranial lesion. CT scans were considered positive if any signs of cranial (skull fracture) or intracranial pathology (hematoma, air, or contusion) were present, subgaleal hematomas were also considered positive to prevent disregarding abnormalities that may influence S100B levels.

Colorectal Cancer Imaging Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols

This retrospective analysis included 81 patients that underwent colorectal surgery for colorectal cancers in our institution in 2016. These patients had undergone contrast-enhanced computed tomography (CT) in a preoperative work-up. All CT images were acquired with a 64-detector row CT scanner (Revolution GSI and Revolution EVO, GE Healthcare, Milwaukee, WI, USA). The CT scan was started at 70 s after an injection of non-ionic contrast agent with iodine. In our institution, we routinely reconstructed thin-slice CT images (1.25-mm thick or occasionally 0.625-mm thick) for rectal cancer cases that required lateral pelvic lymph node dissection.

The CT scan was conducted using a GE Healthcare Revolution GSI^® (Chicago, IL, USA) with the following protocol: helical mode, 2.25 mm slice thickness, 1.25 mm interval, 120 kV, and a maximum of 280 mA from C1 to the top of the head. Additional bone window reconstructions were also performed. To determine whether patients had a trauma-related intracranial lesion, we collected radiological parameters and divided them into two groups: those with no evidence of trauma-related intracranial lesions on CT (ICL−) and those with at least one trauma-related intracranial lesion on CT (ICL+). A CT scan was considered to be positive if there was any evidence of intracranial pathology, such as a hematoma, air, or contusion. Furthermore, patients with an S100B concentration below the decision threshold of 0.10 µg/L who did not undergo a CT scan were classified as ICL due to the high sensitivity of S100B. It is important to note that this classification is objective and based solely on the S100B concentration.

Evaluating Pancreatic Severity in AP

Check if the same lab product or an alternative is used in the 5 most similar protocols

We evaluated the pancreas using CE‐CT (Revolution GSI and Revolution EVO, GE Healthcare Japan, Tokyo, Japan) upon admission to determine the severity of AP. Using CT images, we measured the following body parameters: visceral fat area (VFA); subcutaneous fat area (SFA) at the umbilical level; and psoas muscle area at the level of the third lumbar vertebra (L3) using axial CT slices. We assessed them using the image analysis system SYNAPSE VINCENT (Fujifilm, Tokyo, Japan), which showed that VFA is colored red and SFA is colored blue, and those areas were automatically calculated (Supplementary Fig. S1). The fat area was set to a Hounsfield unit threshold of −150 to −30. We measured psoas muscle area by manual tracing. All images were measured by Y.H. The psoas muscle index (PMI) was calculated by dividing the psoas muscle area by the square of the height.¹⁰

All procedures were completed within the Respiratory Medicine Department, Oxford University Hospitals NHS Foundation Trust. The study visit day included: a medical history assessment, completion of the COPD assessment test (CAT;18 (link) and modified Medical Research Council dyspnoea scale,19 (link) standard pulmonary function tests (PFTs; spirometry, body plethysmography and the single breath test of carbon monoxide uptake; Jaeger MasterScope Body, Carefusion), and the IST. Using the first two questions of the CAT questionnaire an additional symptom score was produced, aiming to specify cough frequency and phlegm/mucus production (Cough + Mucus (C+M) score). In 21 COPD patients and 13 healthy participants (ie, 25% of each group), chest CT scans were obtained within 3 months of the study visit day. Unenhanced low dose CT scans were performed with a 64-slice scanner (Revolution GSI, GE Healthcare) and the following parameters: 0.625mm slice thickness, 60 mA, 100 kV, 40mm tube collimation, 0.984 beam peach, 0.5sec rotational time. Scans were analysed with Pulmonary Toolkit20 to quantify the whole-lung emphysema extent. This was reported as percentage low attenuation area (%LAA), the percentage area of the whole-lung with attenuation values inferior to −950 Hounsfield units.
