Analysis of ILD-RADS reproducibility and validity: Can different degrees of experience affect the interpretation?

Purpose: To evaluate the reliability, validity and applicability of ILD-RADS among readers with different levels of experience.

Methods: This prospective tri-center study included 159 patients with clinically diagnosed ILD who underwent high-resolution CT (HRCT). Two experienced thoracic radiologists, two general radiologists, and one pulmonologist independently evaluated the HRCT images blinded to the patient's clinical data and assigned ILD-RADS category for each patient.

MR imaging of soft-tissue vascular malformations: diagnosis, classification, and therapy follow-up.

Vascular malformations and tumors comprise a wide, heterogeneous spectrum of lesions that often represent a diagnostic and therapeutic challenge. Frequent use of an inaccurate nomenclature has led to considerable confusion. Since the treatment strategy depends on the type of vascular anomaly, correct diagnosis and classification are crucial.

Role of high resolution contrast-enhanced magnetic resonance angiography (HR CeMRA) in management of arterial complications of the renal transplant.

Introduction: Transplant renal artery (RA) stenosis (TRAS) is the most frequent posttransplantation vascular complication. Contrast enhanced magnetic resonance (CeMRA) angiography has been established as the preferred imaging technique for the evaluation of TRAS because it does not require the use of iodinated contrast material and does not expose the patient to ionizing radiation. Digital subtraction angiography (DSA) is the gold standard in the evaluation of arterial tree of the renal allograft.

High spatial resolution magnetic resonance imaging of cystic adventitial disease of the popliteal artery.

High spatial resolution magnetic resonance imaging (MRI) of patients with cystic adventitial disease can demonstrate connections between cysts in the adventitia and the adjacent joint, which is important for successful treatment. The inability to identify these during surgery can lead to a recurrence; thus, high spatial resolution MRI has the potential to affect therapy. This article presents the high spatial resolution MRI findings of cystic adventitial disease in a series of three consecutive patients and discusses the relevance of these findings to the etiology and therapy.

Acute renal allograft failure due to thrombosis of a previously stented iliac artery: salvage using mechanical thrombectomy and restenting.

Background: Renal artery stenosis is the most common surgical complication after renal transplantation. RT stenosis of the iliac artery presents in a similar way. Interventional techniques can salvage the graft in most cases.

Hypothenar hammer syndrome in a computer programmer: CTA diagnosis and surgical and endovascular treatment.

Finger ischemia due to embolic occlusion of digital arteries resulting from trauma to the palmar ulnar artery has been termed hypothenar hammer syndrome (HHS). In HHS, arterial thrombosis and/or aneurysm formation with embolization to the digital arteries causes symptoms of ischemia. We describe a patient in whom the initial diagnosis was made on multidetector computed tomographic angiography (CTA), as well as his endovascular and surgical management.

Recurrent cystic adventitial disease of the popliteal artery: successful treatment with percutaneous transluminal angioplasty.

Cystic adventitial disease (CAD) is a rare vascular condition that most commonly affects the popliteal artery. Percutaneous transluminal angioplasty (PTA) is generally not considered a valid therapeutic option due to high recurrence rate. We report a case of CAD of the popliteal artery that recurred after surgical cyst enucleation that was successfully treated with PTA.

CT angiography of renal arteriovenous fistulae: a report of two cases.

Renal arteriovenous fistulas (AVFs) are rare abnormal communications between the arterial and venous circulations that can be congenital or acquired. We describe the multidetector computed tomography angiography (MDCTA) appearance of 2 cases of renal AVF, one with the cirsoid and one with the aneurysmal subtype, and the impact of these findings on therapeutic decision making and treatment follow-up.
