Lung CT Imaging Protocol for COVID-19 Diagnosis

Each patient was placed in the supine position on the CT machine (uCT760 or Umi780, United Imaging, Shanghai, China; Precison32, Campo imaging, Shenyang, China) and scanned during the inspiratory phase. Images were reconstructed with a slice thickness of 1 mm and an interval of 1 mm.
Lung CT images were screened by three imaging physicians who were blind to the RT-PCR results and clinical information. The CT images were independently read by two radiologists with more than 5 years’ experience in the diagnosis of chest CT scans. In case of dispute, they discussed and reached a consensus that was reviewed by a senior imaging physician with more than 10 years of experience.

All scans were performed with patients in the supine position during end-inspiration without intravenous contrast on three CT scanners: uCT 760, uMI 780 scanners (United Imaging; Shanghai, China) and Precision 32 (CAMPO Imaging; Shenyang, China). Images were obtained from the apex to lung bases, using a standard dose protocol, reconstructed at 1.0 mm/1.1 mm slice thickness, with 0.7 mm increment, 512 × 512 mm and a sharp reconstruction kernel. The lung window width and level settings were 1500 Hounsfield units (HU) and −600 HU.

PSMA-11(HBED-CC) was purchased from ABX (Germany). ⁶⁸Ga-PSMA-11 was radiolabeled using the automated labeling module produced by ITM (Germany). The radiochemical purity was > 99%. The synthesis procedure was reported previously.^{[11 (link)]} Whole-body PET/CT (uMI780, United Imaging, China) was performed from the vertex to the proximal legs 1 hour postinjection of ⁶⁸Ga-PSMA-11 (111–185 MBq). Attenuation-corrected images were assessed clinically by certified nuclear medicine physicians.

From participating sites, we collected baseline ¹⁸F-FDG PET/CT images in the DICOM format. Patients with normal blood glucose levels were asked to fast, stop receiving intravenous glucose, and avoid severe activity or extended exercise for 6 h before intravenous ¹⁸F-FDG (3.7 MBq/kg) delivery. A hybrid PET/CT scanner (uMI780, United Imaging Healthcare, Shanghai, China) was used for all PET/CT imaging which included a low-dose CT scan (current 120 mA; tube voltage 120 kV; matrix 512 × 512 pixels; slice thickness 3.00 mm; window width 300–500 HU; window level 40–60 HU) and a PET scan (with 1.5 min/position in 3D acquisition mode and 5–6 bed positions), and it performed less than one hour after radiotracer injection as part of the scanning procedure. The PET image was reconstructed using attenuation iterative correction approach (Ordered Subsets Expectation Maximization, OSEM) and the window width and window level of the CT images were set to 350 and 50 then submitted to the MedEx workstation together with fusion imaging once all the patient's PET/CT image parameters had been standardized.

For [¹⁸F]FDG PET/CT image acquisition, patients fasted for at least 6 hours and the plasma glucose level was lower than 11 mmol/L (about 200 mg/dL) (10 (link)). After an intravenous injection of [¹⁸F]FDG 3.7 MBq/kg, the patient rested in a quiet place. The patients were instructed to drink 500 mL of water to stimulate [¹⁸F]FDG excretion in the renal calyx and to urinate before scanning. Data were acquired using a PET/CT scanner (uMI780, United Imaging, Shanghai, China) 45 to 60 minutes after intravenous administration. First, a CT scan was performed from the head to the upper thigh (tube current of 120 mA, tube voltage of 120 kV, and slice thickness of 3.00 mm). PET was then performed at the same bed position as the CT scan, 5-6 bed positions, and 3D acquisition mode at 1.5 min/position. [⁶⁸Ga]Ga-DOTA-FAPI-04 PET/CT was performed within 7 days of [¹⁸F]FDG PET/CT for comparison and the dose of [⁶⁸Ga]Ga-DOTA-FAPI-04 injected was calculated based on patient body weight (1.85 MBq/kg). Other parameters of CT or PET were the same as [¹⁸F]FDG PET/CT, except that [⁶⁸Ga]Ga-DOTA-FAPI-04 PET imaging was acquired at 3.0 min/position. After the reconstruction was complete, image analysis was performed using the joint imaging post-processing fusion software.

Prior to the examination, all patients were mandated to fast for a minimum of 6 hours prior to examination. ¹⁸F-FDG was manufactured in line with standards set by our hospital, utilizing a 112-ring digital light guide PET/CT scanner (uMI780, United Imaging, China). The radiochemical purity was maintained at 98%, with the final products being diluted with saline and sterilized via a 0.22-μm Millipore filter through a sterile syringe. Doses of intravenously injected ¹⁸F-FDG were calculated utilizing each patient’s weight (3.7 MBq [0.1 mCi/kg]). The bounds for the images were set to CT scan from the head to upper thighs. PET scans were performed promptly post CT scan with 1.5 minutes of scanning time per image, utilizing 3-D mode for all images.
Two experienced nuclear medicine physicians (YW and JJW) examined all PET/CT images. For quantitative analysis, the SUVmax-PT was normalized to body weight and automatically calculated for the primary tumor. TLG-PT was calculated using SUVmean × MTV (metabolic tumor volume, whcih recorded at the absolute SUV threshold of 2.5 and the relative SUVmax-PT threshold of 70%). In the current study, we did not include SUVmax and TLG for the neck lymph nodes in the analysis, given that neck lymph node inflammation and the complex biology of lymph nodes may inadvertently influence the results of the research.23 (link)

The PET/CT scans were obtained 60 min after the intravenous injection of 111–185 MBq [⁶⁸Ga]Ga-DOTA-FAPI-04. All PET/CT images were acquired from the head to the upper thighs. The CT scans were performed with a tube voltage of 120 kV, an effective tube current of 70–200 mAs (Dose Modulation (uMI780, United-Imaging Healthcare)), and a slice thickness of 3 mm. PET scans were immediately performed after the CT scan in 3D acquisition mode (matrix: 192×192) with 4–5 bed positions and 2 min/position. PET data were reconstructed iteratively (2 iterations and 20 subsets) with CT data for attenuation correction, and the PET/CT images were then coregistered and displayed using dedicated software (Image Fusion software, UIH).

All images were acquired with a digital PET/CT scanner (uMI780, United Imaging Healthcare, Shanghai, China) equipped with lutetium–yttrium orthosilicate crystal coupled with silicon (Si) photomultipliers (PM). The patients were asked to fast a least 6 h before the PET/CT examination. The patients received an injection of the ¹⁸F-FDG solution according to their body weight (5.0 MBq/kg). The PET/CT examination was started 60 min after the injection. The phantom and the patients underwent a CT scan using a tube voltage of 120 kVp and a tube current of 250 mAs with automatic modulation, followed by a whole-body PET scan with an emission time of 2 min per bed position from the skull base to the upper thigh of the patient or about 30 cm long to cover the whole phantom.

Patients were asked to fast for a minimum of six hours prior to PET/CT scans. PET/CT imaging was conducted via a 112-ring digital light guide PET/CT (uMI780, United Imaging, China) according to published guidelines for PET/CT imaging 12 (link). Helical CT was implemented from the head to proximal thigh prior to PET procurement based on the standardized protocol. Static acquisitions from head to proximal thigh were obtained 45 minutes post ¹⁸F-FDG injection and lasted for a period of 15 minutes. Dynamic acquisitions were done as follows: imaging started at the time of injection of ¹⁸F-FDG (3.75 MBq/kg produced from Guangzhou Atom High Tech Radiopharmaceutical Co.,Ltd., Guandong Province, China) and continued for 60 minutes. Dynamic scans were conducted from the lung apex to the liver for the COVID-19 group and control group 2. Each dynamic PET study lasted 60 minutes that contained 48 frames (time × frame: 5s × 18, 10s × 6, 30s × 5, 60s × 5, 150s × 8, 300s × 6) and was adjusted for isotope decay, scattering events, and random coincidence.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
