OBJECTIVE To explore a method of establishing a rabbit model of superior vena cava obstruction (SVCO) by injecting VX2 tumor cell suspension transcutaneously under ultrasound guidance. METHODS A suspension of VX2 tumor cells was prepared under sterile conditions. Fifteen adult healthy New Zealand White rabbits were enrolled in the experiment. Under ultrasound guidance, about 0.1 ml of the liv...

Stethoscope evaluation of the lungs is widely accepted and practiced; however, there are some widely recognized, major limitations with its use. A safe device that helped solve these limitations by translating sound into objective, quantifiable images would have clinical utility. Translating lung sounds into quantifiable images in which regional differences or asymmetry in intensities of breath...

Objective: To evaluate the reliability of ultrasound for detection rheumatoid arthritis (RA). Study Design: Systematic Review. Setting: The University Lahore. Period: 2001 to 2021. Material & Methods: A systematic exploration literature was achieved by collecting articles related our topic. Articles reporting result assessment ultrasonography were included in this study. Exclusion criteria ...

BACKGROUND To evaluate color Doppler imaging (CDI) as the primary imaging modality in the diagnosis of pediatric orbital capillary hemangioma. METHODS This is a retrospective study of 36 consecutive cases of orbital capillary hemangiomas between January 2006 and July 2011. Data on demographic details, clinical findings, gray-scale ultrasonography, CDI characteristics, treatment, and follow-up...

OBJECTIVE This study compares the clinical, ultrasonography, radiography, and laboratory outcomes of painless and painful chronic synovitis in patients with established rheumatoid arthritis. METHODS This cross-sectional study involved 60 patients with rheumatoid arthritis and synovitis in the metacarpophalangeal joints; 30 of the patients did not experience pain, and 30 had experienced pain f...

Acardiac-acephalic twin is one of the bizarre complications of monozygotic, monochorionic twin pregnancies. It is commonly referred to as Twin Reversed Arterial Perfusion (TRAP) sequence, in which the primary malformation is the lack of a well -defined cardiac structure in one twin (acardiac), which is kept alive by its structurally normal co-twin (pump twin) through abnormal placental vascular...

To retrospectively evaluate the diagnostic performance of shear wave elastography (SWE) and thyroid imaging reporting and data system (TI-RADS) in differentiating malignant and benign thyroid nodules. A total of 313 thyroid nodules in 227 patients were included. All thyroid nodules were underwent SWE and TI-RADS before fine needle aspiration biopsy and/or surgery. SWE elasticity indices of the ...

OBJECTIVE To show an artifact related to color Doppler flow imaging of the orbit. METHODS Three patients with strongly reflective structures in the orbit were selected from those routinely referred by clinicians for color Doppler ultrasonography of the orbit. Gray scale and color flow images were obtained with a 7.5-MHz linear array probe for a region with strongly reflective structures. A sp...

Musculoskeletal ultrasound imaging can be used to investigate the skeletal muscle structure in terms of architecture (thickness, cross-sectional area, fascicle length and fascicle pennation angle) and texture. Gray-scale analysis is commonly used to characterize transverse scans of the muscle. Gray mean value is used to distinguish between normal and pathologic muscles, but it depends on the im...

Adnexal masses are spectrum of diseases from benign non neoplastic and neoplastic masses to malignant neoplasms. Endovaginal ultrasonography (US) is the fisrt and invaluable modality for assessment of adnexal masses because it is available and has a high negative predictive value. Important morphologic features are solid (vascularized) tissue, vascular and thick septations, and papillary projec...
