“…11 In the testes of a healthy volunteer, the RI is rarely less than 0.5, but in patients with epididymo-orchitis, more than half have an RI of less than 0.5. 12 The waveform in the contralateral testis may or may not be helpful depending on whether the process is unilateral or bilateral.…”

Objective. To illustrate how spectral Doppler waveform analysis plays an adjunctive but very definite role in scrotal sonography. Methods. The cases illustrate a variety of testicular disorders that were collected at a referral tertiary care center. Results. Normal and a variety of pathologic conditions of the testes are discussed, along with their signature spectral waveforms. Conclusions. Analysis of the spectral waveform provides important additional information in various scrotal disorders with acute pain. Spectral waveform analysis is critical to diagnosing incomplete torsion when color and power Doppler examinations are indeterminate. Key words: arteriovenous malformation; varicocele; epididymoorchitis; resistive index; spectral Doppler sonography; testis; torsion. onography is the primary modality for evaluating scrotal disorders. Color, power, and spectral Doppler sonography are extensively used for evaluating patients with a painful scrotum. 1-3 Frequency spectrum analysis is an essential element of vascular sonography. Sonographers and sonologists should be familiar with the various subtle variations in spectral waveforms and the enormous amount of information provided by this technique. The purpose of this presentation is to illustrate how spectral waveform analysis plays an adjunctive but very definite role in scrotal sonography. Normal Spectral Doppler CharacteristicsThe spermatic cord contains the testicular artery, the artery to the vas deferens, and the cremasteric artery supplying blood to the testis, epididymis, and scrotal wall, respectively. In descending order, they arise from the abdominal aorta, superior vesicle artery, and inferior epigastric artery. 1,4 Proper interpretation of velocity waveforms requires an understanding of the normal waveform characteristics of a given vessel and of the physiologic status of the circulation subtended by the vessel. The normal spectral waveform of the testicular artery and artery supplying the epididymis is a lowresistance, high-flow pattern (Figure 1), whereas that of the cremasteric artery supplying the scrotal wall has a high-resistance, low-flow pattern (Figure 2). 5,6

“…There is an absence of colour Doppler flow and contrast enhancement. The diagnosis should also be suspected when reversal of intratesticular arterial flow in diastole is observed with an associated focal abnormality [15]. CEUS demonstrates clear demarcation of avascular areas to allow for appropriate clinical management [16].…”

ABSTRACT. The aim of this review is to illustrate the potential of different and newer ultrasound techniques beyond conventional B-mode imaging, including colour Doppler ultrasound, contrast-enhanced ultrasound (CEUS) and tissue elastography, in the characterisation of both benign and malignant intratesticular lesions. Normally, testicular malignancies, either primary or secondary, demonstrate an increase in colour Doppler signal. However, there is a diversity of benign testicular lesions that may mimic testicular malignancies. The use of CEUS improves characterisation of testicular lesions, and confirms lack of vascularity in benign abnormalities such as epidermoid cysts, infarctions, abscesses and changes following trauma. Tissue elastography allows further evaluation of the cellular consistency of the abnormality. Familiarity with the appearances seen with these ultrasound techniques in both benign and malignant abnormalities should aid in improving confidence in arriving at the correct diagnosis.

Ultrasonography performed with a high-frequency transducer is the modality of choice for evaluating acute and nonacute scrotal disease. Acute epididymitis and epididymo-orchitis are the most common conditions that present with acute scrotal pain. Differentiation of these from testicular torsion is important for determining the appropriate management. High-transducer sonography allows the visualization of the epididymis and its detailed anatomy. We present important sonographic features of epididymitis and epididymo-orchitis caused by infectious and noninfectious etiologies. Features of benign and malignant epididymal lesions, including epididymal cysts, spermatoceles and tubular ectasia, sperm granulomas, adenomatoid tumors, leiomyomas, papillary cyst adenomas, lymphoma, and metastases are also presented. In addition, epididymal trauma and torsion are discussed. The goal of the review is to provide the radiologist with a better understanding of the numerous pathological conditions that occur in the epididymis.
