Digital Ischemic Loss in Systemic Sclerosis
Table 2
Radiographic considerations for evaluation of digital ischemic loss in patients with systemic sclerosis.
| Modality | Pros | Cons |
| Conventional Angiography | Extremely sensitive for identifying vascular abnormalities | Invasive | High contrast load | Standardized technique | Radiation exposure | Risk of inducing vasospasm |
| Magnetic Resonance Angiography (MRA) | Standardized technique | | Noninvasive | | No contrast load | Long scanning time | No radiation exposure | Resolution inferior to CT or conventional angiography in distal digital vessels | Can visualize vessel wall in addition to lumen | | Can visualize surrounding structures | | Can visualized venous lesions | |
| Computed Tomography (CT) Angiography | Noninvasive | Less contrast load than conventional angiography | Excellent bone and soft tissue spatial relationships | Shorter scanning time | | Resolution inferior to conventional angiograpy in distal digital vessels |
