Multi-modality photoacoustic/ultrasound imaging based on a commercial ultrasound platform.

Opt Lett 2021 Sep;46(17):4382-4385

Multimodal imaging takes advantage of each modality and has become a recent trend in the field of biomedical imaging. In this Letter, we develop and evaluate an integrated multi-modality imaging system combining photoacoustic computed tomography, optical resolution photoacoustic microscopy, brightness mode, and power Doppler ultrasound imaging on a commercial ultrasonographic platform. Using different imaging modalities enables the hybrid system to recover dense vascular networks and hemodynamic and morphological variations in both superficial and deep tissues. Read More

A Step-by-Step Sonographic Approach to Vascular Anomalies in the Pediatric Population: A Pictorial Essay.

Indian J Radiol Imaging 2021 Jan 13;31(1):157-171. Epub 2021 May 13.

Department of Radio-Diagnosis, Lady Hardinge Medical College and Associated Hospitals, New Delhi, India.

Vascular anomalies are a common cause of soft-tissue masses in children and often referred for ultrasonographic (USG) evaluation. They are broadly classified as vascular tumors (hemangiomas, hemangioendotheliomas, and angiosarcomas) or vascular malformations (venous malformations, lymphatic malformations, and arteriovenous malformations). Findings on USG and Doppler imaging can be used to categorize vascular anomalies into high- or low-flow lesions, which forms the basis for further workup, diagnosis, and management. Read More

A case of eosinophilic gastroenteritis with high PET-CT accumulation treated by P-CAB.

Radiol Case Rep 2021 Aug 12;16(8):2174-2178. Epub 2021 Jun 12.

Department of General Surgery, Kawasaki Medical School, Okayama, Japan.

Eosinophilic gastroenteritis (EGE) can present findings on computed tomography (CT) images that resemble malignant tumors. EGE is generally treated with systemic oral steroid administration, which is reportedly effective in relieving symptoms at least temporarily. Here, we report a case of EGE that mimicked malignant lymphoma in a gastroduodenal lesion, in which treatment with a potassium-competitive acid blocker without systemic oral steroid administration relieved the symptoms and reversed the initial image findings.

Diagnosis and spontaneous healing of asymptomatic renal allograft extra-renal pseudo-aneurysm: A case report.

World J Clin Cases 2021 Jun;9(16):3943-3950

Department of Ultrasound, Beijing Friendship Hospital, Capital Medical University, Beijing 100050, China.

Background: Transplant renal artery stenosis is a relatively frequent vascular complication after transplantation. However, extra-renal pseudo-aneurysms (EPSAs) are rare after transplantation; they can be life-threatening and usually need open surgical repair. We discuss the diagnosis and spontaneous healing of an asymptomatic renal allograft EPSA caused by renal artery anastomotic stenosis, which was diagnosed in a timely manner and managed by conservative treatments.

What is the role of ultrasonography in the early diagnosis of scaphoid fractures?

Eur J Radiol Open 2021 23;8:100358. Epub 2021 May 23.

Universidad CES, Antioquia, Cl. 10a #22 - 04, Medellín, Colombia.

Scaphoid fractures are the most prevalent type of carpal bone fractures. High-spatial-resolution sonography detects direct signs of scaphoid fractures such as scaphoid cortical disruption; nevertheless, indirect signs such as radiocarpal effusion and scapho-trapezium-trapezoid effusion can also be visible. The diagnosis is performed when both direct and indirect signs of scaphoid fracture are presented. Read More
