CT Venography: Technique and Indications
VENOUS CT Venography: Technique and Indications A brief summary of how to perform indirect and direct CT venography and when this imaging modality can be helpful in diagnosing venous disease. BY ANA MARIJA ALDUK, MD, PHD, AND GERARD O’SULLIVAN, MD T venography (CTV) is not a particularly well- A B validated technique, with most data derived from anecdotal experience. For a variety of reasons, CTV has become the go-to imag- Cing modality for a quick and efficient answer to most venous problems. For example, we work in a trauma center with a large oncology population, and we have learned that oftentimes ultrasound simply doesn’t cut it, particularly in the context of intra-abdominal C D malignancy. Even in very experienced hands, things can be missed. CTV/contrast-enhanced CT provides multiple extra levels of information, including the presence or absence of inferior vena cava (IVC) filters; the condition of the IVC, renal veins, collaterals, and internal iliac veins; potential iliac vein compression or Figure 1. CTPA showing massive bilateral PE (A). Indirect CTV nutcracker syndromes; presence of pelvic varicosities; demonstrates acute IVC thrombosis (B), right external iliac as well as ovarian vein thrombosis and undiagnosed vein scarring due to previous DVT (C), and right common malignancy. femoral vein thrombosis (D). TECHNIQUE A C Indirect CTV Often combined with CT pulmonary angiography (CTPA) in the acute setting, indirect CTV is performed as a standard, nonoral, post–intravenous contrast- enhanced CT at approximately 120 to 150 seconds after injection of contrast, which is considerably later than portal venous phase. -

Magnetic Resonance Angiography (MRA) and Magnetic Resonance Venography (MRV) Medical Policy The content of this document is used by plans that do not utilize NIA review. Service: Magnetic Resonance Angiography (MRA) and Magnetic Resonance Venography (MRV) PUM 250-0027-1712 Medical Policy Committee Approval 12/11/2020 Effective Date 01/01/2021 Prior Authorization Needed Yes Description: Magnetic Resonance Angiography (MRA) and Magnetic Resonance Venography (MRV) use Magnetic resonance imaging (MRI) technology to produce detailed 2-dimensional or 3- dimensional images of the vascular system and may be tailored to assess arteries or veins. It is often used for vascular conditions where other types of imaging are considered inferior or contraindicated, and to decrease risk of cumulative radiation exposure and often instead of invasive procedures. Indications of Coverage: A. MRA/MRV is considered medically necessary for the anatomical regions listed below when the specific indications or symptoms described are documented: 1. Head/Brain: a. Suspected intracranial aneurysm (ICA) or arteriovenous malformation (AVM). Any of the following: 1. Acute severe headache, severe exertional headache, or sudden onset of explosive headache, in individuals with signs / symptoms highly suggestive of a leaking/ruptured internal carotid artery or arteriovenous malformation. 2. Known subarachnoid hemorrhage or diagnosis of spontaneous intracerebral hemorrhage with concern for underlying vascular abnormality. 3. Suspected arteriovenous malformation (AVM) or dural AV fistula in an individual with prior indeterminate imaging study 4. Thunderclap headache with question of underlying vascular abnormality AND prior negative workup to include EITHER i. negative brain MRI, OR ii.

Intravascular Ultrasound for Coronary Vessels Policy Number: MP-091 Last Review Date: 11/14/2019 Effective Date: 01/01/2020
Intravascular Ultrasound for Coronary Vessels Policy Number: MP-091 Last Review Date: 11/14/2019 Effective Date: 01/01/2020 Policy Evolent Health considers Intravascular Ultrasound (IVUS) for Coronary Vessels medically necessary for either of the following indications: 1. IVUS of the coronary arteries (consistent with the 2011 ACCF/AHA Guidelines for Percutaneous Coronary Intervention (PCI) 5.4.2) is indicated for any of the following medical reasons: a. To confirm clinical suspicion of a significant left main coronary artery stenosis when standard angiography is indeterminate; b. To detect rapidly progressive cardiac allograft vasculopathy following heart transplant; c. To determine the mechanism of stent thrombosis or restenosis; d. To assess non-left main coronary arteries with angiographic intermediate stenosis (50-70%) to aid the decision whether or not to place a stent; or, e. To assist in guidance of complex coronary stent implementation, especially involving the L main coronary artery. 2. In lieu of coronary angiography when performed to minimize use of iodinated contrast material in an individual with compromised renal function, congestive heart failure or known contrast allergy. Limitations Coronary IVUS is not covered for any of the following (this is not an all-inclusive list): 1. Screening for coronary artery disease in asymptomatic individuals; 2. Routine lesion assessment is not recommended when revascularization with PCI or Coronary Artery Bypass Grafting (CABG) is not being considered; 3. Carotid stent placement; 4. Follow-up monitoring of medical therapies for atherosclerosis; 5. Peripheral vascular intervention; or, 6. Evaluation of chronic venous obstruction or to guide venous stenting. Background Ultrasound diagnostic procedures utilizing low energy sound waves are being widely employed to determine the composition and contours of nearly all body tissues except bone and air-filled spaces. -

Clinical Guideline Optical Coherence Tomography (OCT)
Clinical Guideline Guideline Number: CG025, Ver. 2 Optical Coherence Tomography (OCT) Disclaimer Clinical guidelines are developed and adopted to establish evidence-based clinical criteria for utilization management decisions. Oscar may delegate utilization management decisions of certain services to third-party delegates, who may develop and adopt their own clinical criteria. The clinical guidelines are applicable to all commercial plans. Services are subject to the terms, conditions, limitations of a member’s plan contracts, state laws, and federal laws. Please reference the member’s plan contracts (e.g., Certificate/Evidence of Coverage, Summary/Schedule of Benefits) or contact Oscar at 855-672-2755 to confirm coverage and benefit conditions. Summary Optical Coherence Tomography, or “OCT”, is a medical imaging test that uses light waves to capture live 3-dimensional images. It is similar in principle to ultrasound (which uses sound echoes, rather than light wave reflections), however OCT provides up to 10 times the resolution. OCT has been used to image different structures of the body, including the eye, the heart, the gastrointestinal (GI) system, the breast, and the upper airway. It does not require any contact with the target surfaces and does not produce any ionizing radiation. In some cases, OCT can be used with other instruments such as an endoscope in the GI system or as an intravascular device in the arteries of the heart. OCT is a relatively novel technology and is rapidly evolving in both technique and clinical utility. This guideline provides the clinical criteria and exclusions for the currently supported clinical applications of Optical Coherence Tomography.
