“…Namely, on MDCTA, vasculitis presents with long-segmental stenosis characterized by the smooth luminal tapering (differing from the wall irregularities in atherosclerotic vessels) and circumferential wall thickening with enhancement. When vasculitis is suspected, it is essential to include a delayed phase acquisition in the MDCTA imaging protocol to depict mural enhancement [21].…”

“…In most cases, Doppler ultrasonography (US) is the first imaging modality to be performed. Computed tomography angiography (CTA) or magnetic resonance imaging (MRI) is indicated to improve lesion characterisation and treatment guidance [1,2]. MRI protocols should in most cases not only include conventional sequences but also contrastenhanced magnetic resonance angiography (MRA), which improves the evaluation of the vascular network and helps to characterise vascular malformations [3][4][5].…”

“…MRI is also the imaging method of choice for the evaluation of vascular tumours and the determination of their anatomic extent [6,7]. CTA is versatile and most often used for the evaluation of traumatic lesions and vascular occlusion [2,8,9]. Recently, the clinical availability of advanced CT imaging techniques, such as dynamic CTA and superhigh-resolution (SHR)-CTA, has increased.…”

Vascular lesions of the hand are common and are distinct from vascular lesions elsewhere because of the terminal vascular network in this region, the frequent hand exposure to trauma and microtrauma, and the superficial location of the lesions. Vascular lesions in the hand may be secondary to local pathology, a proximal source of emboli, or systemic diseases with vascular compromise. In most cases, ischaemic conditions are investigated with Doppler ultrasonography. However, computed tomography angiography (CTA) or dynamic contrast-enhanced magnetic resonance angiography (MRA) is often necessary for treatment planning. MR imaging is frequently performed with MRA to distinguish between vascular malformations, vascular tumours, and perivascular tumours. Some vascular tumours preferentially affect the hand, such as pyogenic granulomas or spindle cell haemangiomas associated with Maffucci syndrome. Glomus tumours are the most frequent perivascular tumours of the hand. The purpose of this article is to describe the state-of-the-art acquisition protocols and illustrate the different patterns of vascular lesions and perivascular tumours of the hand.

“…Non-invasive techniques as CTA and Doppler can accurately evaluate for Upper extremity stenotic or embolic events, mainly when they affect proximal vessels. Their minimal invasiveness, wide availability, rapid acquisition, and display of both vascular and soft tissue structures (Bozlar et al, 2013).…”

Ischemia at the upper extremity is considered one of the disabling and frequent causes of blind medical care failure. Non- invasive techniques as CTA and Doppler could effectively determine stenosis grades up to occlusion of the upper extremity, particularly if they impact the vessels proximal to the wrist also they can characterise the thrombus characters and recanalisation. The study was a prospective study carried out on 30 patients with upper extremity ischemia during the period from April 2019 to April 2020 at the Radiology department of ZagazigUniversity hospitals. All patients presented with signs of ischemia as claudication, colour changes, pulselessness and their age ranged between 45 to 70 years. All patients underwent complete history taking and clinical examination, the results were correlated to conventional angiography. Overall, in the present study, Doppler US has a sensitivity of 86.6 %, a specificity of 100%, PVP of 100% and PVN of 91.3%. CTA has a sensitivity of 93.3 %, the specificity of 100%, PVP of 100% and PVN of 95.45 %.CTA was more sensitive in milder degrees (Grades I& II) of thromboembolism and stenosis but no significant difference in severe cases (Grades III &IV). Segmental length assessment and collateral circulation were better noted on CT Angiography.
