Doppler Ultrasonographic Evaluation of Erectile Dysfunction in a Northern Nigerian Tertiary Hospital.

Background: Colour duplex Doppler is a noninvasive tool for the evaluation of the vascular mechanism of erectile dysfunction (ED). It can be used to determine the integrity of the vascular mechanism and to differentiate between arterial and venous insufficiency.

Objectives: To identify the vasculogenic causes of ED and subclassify them into arteriogenic, venogenic, or mixed to assist in predicting the clinical outcome.

Efficacy of Computed Tomography and Ultrasonography in Diagnosis of Metastatic Cervical Lymph Nodes in Orofacial Cancer.

Introduction: There is no consensus on which imaging modality is better for the detection of metastatic cervical lymph nodes in orofacial malignancies. This study evaluates the efficacy of computed tomography (CT) and ultrasonography (US) in diagnosis of metastatic cervical lymph nodes in orofacial cancer.

Materials And Methods: Sixty patients with various histologically diagnosed orofacial malignant lesions and clinical evidence of cervical lymph node metastasis were examined using US and CT.

Doppler ultrasonographic evaluation of lower limbs deep-vein thrombosis in a teaching hospital, Northwestern Nigeria.

Background: Deep-venous thrombosis (DVT) of lower limbs is one of the most common causes of death caused by pulmonary embolism. Many medical and surgical disorders are complicated by DVT. B-mode and color Doppler imaging are needed for the early diagnosis of DVT to prevent complications and sequalae of DVT.

Accuracy of ultrasonography in the evaluation of abdominal masses in children in Nigeria.

Introduction: Abdominal masses in children constitute a spectrum of lesions of diverse origin, nature and significance. In a low-income setting with limited investigative facilities, accurate diagnosis of abdominal masses can be very challenging. However, ultrasound has been used preferentially as a diagnostic tool in evaluating abdominal masses in children.

Colour doppler sonography of the penis in the evaluation of erectile dysfunction: Our experience in Abuja, Nigeria.

Background: Erectile dysfunction (ED) is an inability to achieve and maintain erectile rigidity sufficient for satisfactory sexual performance. It is either organic or psychogenic in origin. This study was aimed at establishing vasculogenic causes among patients being evaluated for ED using triplex Doppler Ultrasound.
