Background and Aims: Venous Thrombo Embolism (VTE) refers to the formation of clots in blood vessels. The current study aimed to investigate deep vein thrombosis (DVT) by imaging modalities. Materials and Methods: In this review study, national databases, including Magiran, SID, IranMedex, as well as international ones, namely databases including PubMed, Google scholar, Scopus, and ISI, were searched for related books and articles.  The keywords included thrombosis, deep vein thrombosis, imaging, and thrombosis detection. Results: In patients with suspected primary or recurrent deep vein thrombosis, CT venography (CTV) and Magnetic Resonance Venography (MRV) are rarely used on suspicion of iliac vein thrombosis or inferior vena cava (IVC) thrombosis in ultrasound. These examinations have relatively poor reliability, cause adverse side effects of radiation and contrast materials, and are undoubtedly more costly.   Conclusion:  As evidenced by the obtained results, different methods are available for the diagnosis of deep vein thrombosis. Moreover, it was revealed that ultrasound imaging is the most reasonable method for initial examination due to its sensitivity, specificity, costs, and adverse effects.
