Individually Optimized Uniform Contrast Enhancement in CT Angiography for the Diagnosis of Pulmonary Thromboembolic Disease

Examine the feasibility and efficacy of individually optimized uniform contrast enhancement
in CT pulmonary angiography (CTPA) for the diagnosis of pulmonary thromboembolic disease.

Patient characteristics, qualitative image quality scores, and quantitative contrast
enhancement and CNR will be described using mean values and standard deviations for
continuous variables, and frequencies and percent for categorical variables. Difference
between the two patient groups will be compared using Wilcoxon signed rank tests and
chi-square statistics for continuous and categorical variables, respectively. All
statistical tests will be performed at a significance level of 0.05.

Inclusion Criteria:

- Patients 18 years old or older

- Patients who have been recommended for CTPA scan for the diagnosis of pulmonary;
thromboembolic disease (PE) in the Department of Diagnostic Radiology and Nuclear
Medicine at the University of Maryland-Patients whose body mass index (BMI) is
greater than 30 kg/m2.

- Patients whose body mass index (BMI) is greater than 30 kg/m2

- Patients who signed the University of Maryland Medical Center Consent for Intravenous
Contrast Administration

Exclusion Criteria:

- Pregnant or breast-feeding women; Female participants of childbearing age (10 - 60
years) will be screened for their pregnancy status prior to study registration, by
following the Department of Diagnostic Radiology and Nuclear Medicine CLINICAL
STANDARD Procedure DI-AOP-003 "Pregnancy Screening Documentation"; - Patients with
decreased renal function34-36. This is evaluated by blood work checked within 30 days
prior to the CTPA scan with contrast. Patients cannot receive contrast if their BUN
index is not within [7-20] or creatinine is not within [0.5 - 1.4] mg/dL

- Patients with decreased renal function34-36. This is evaluated by blood work checked
within current admission for inpatients or within 30 days for outpatients prior to
the CTPA scan with contrast. Patients cannot receive contrast if their serum
creatinine level exceeds 2.0 mg/dL

- Patients with known moderate or severe allergic reactions to contrast, including but
not limited to: shortness of breath, a change in baseline vital signs, such as a
change in blood pressure, tachycardia, increased respirations that can progress to
major respiratory distress, laryngeal edema, bronchospasm, arrhythmias, convulsions,
and cardiopulmonary arrest.
