PENILE DOPPLER WITH TABLET/INJECTION ULTRASOUND SCAN

What this scan checks and why it matters

• Blood flow velocity in the penile arteries
• Venous leak that prevents sustained erections
• Plaque or scarring (Peyronie’s) that may block circulation

How Cadabams Diagnostics simplifies the process

• Same-day appointments
• Private, sound-proof rooms
• Immediate digital report emailed to you and your doctor

What is Penile Doppler with Tablet/Injection Ultrasound Scan?

Definition and technology behind Doppler ultrasound

A high-frequency sound-wave probe measures how fast blood moves through the cavernosal arteries—no X-rays, no radiation.

Role of tablet or injection (vasodilator)

• Tablet option: dissolve sildenafil under the tongue to encourage natural erection
• Injection option: a tiny dose of prostaglandin E1 is delivered with an insulin-type needle for faster, reliable results

Difference between standard ultrasound and penile Doppler

Standard imaging shows shape; Doppler adds motion, revealing direction and speed of blood flow critical for diagnosing vascular ED.

Types of Penile Doppler Scans

• Color Doppler ultrasound scan – maps arteries in red/blue
• Spectral Doppler waveform analysis – graphs velocity curves
• Dynamic infusion pharmacocavernosometry – optional stress test for venous leak

• Persistent ED after lifestyle changes
• Pre-surgical planning (penile implant, vascular bypass)
• Post-trauma evaluation (fracture or pelvic injury)
• Peyronie’s disease with suspected vascular compromise

Symptoms that prompt referral

• Erections too weak for penetration
• Loss of erection quickly despite stimulation
• Delayed onset (>10 min) after arousal

Age groups commonly screened

• 25–40 yrs: early vascular disease or trauma
• 40–60 yrs: most common, often linked to diabetes or hypertension
• 60+ yrs: pre-surgical assessment before implants

Distinguishing vascular vs. psychogenic erectile dysfunction

A normal Doppler with rapid erection suggests psychological causes; reduced flow confirms arterial or venous issues.

Benefits of Taking the Penile Doppler Ultrasound

• Non-invasive with real-time imaging
• Guides targeted treatment (medication, stent, or implant)
• Reduces trial-and-error of oral drugs
• Restores confidence with objective data

Illnesses Diagnosed with Penile Doppler Ultrasound

• Arteriogenic erectile dysfunction – clogged penile arteries
• Venous leak – blood escapes too quickly
• Peyronie’s plaque with vascular compression
• Post-traumatic arterial insufficiency

• No overnight fasting required
• Shave or trim pubic hair for probe contact
• List current medications, especially nitrates or anticoagulants
• Bring ID and any prior lab reports

Pre-requisites & Best Time to Take the Scan

• Stable BP and pulse (<140/90 mmHg, HR 60–100)
• Morning slots reduce stress and caffeine levels
• Avoid smoking and coffee 4–6 hrs before test

Eligibility

Ideal candidates

• Adult males ≥18 yrs with suspected vascular ED

Contra-indications

• Severe unstable angina or MI within 3 months
• Known hypersensitivity to alprostadil or sildenafil

Procedure for Taking a Penile Doppler Ultrasound

1. Privacy assured: supine on cushioned exam table with drapes.
2. Baseline scan: grayscale imaging of corpora cavernosa.
3. Stimulation: tablet under tongue OR micro-injection at base.
4. Monitoring: continuous Doppler for 20–30 min; technician captures waveforms at 5-min intervals.
5. Documentation: color snapshots and PSV/EDV readings stored on cloud portal.

Caution Before Taking the Test

• Inform staff if on warfarin, DOACs, or antiplatelets.
• Report history of priapism (>4 hrs).
• Arrange ride home if choosing injection option (rare dizziness).
