前列腺影像学与治疗

皇冠hga025大学洛杉矶分校健康 approach to prostate imaging and treatment

皇冠hga025大学洛杉矶分校健康 radiologists offer comprehensive and sophisticated imaging to evaluate and diagnose prostate disease. We work closely with referring health care providers, offering expertise in prostate cancer diagnosis, 治疗及后续护理.

我们课程的亮点包括:

先进的技术: We use leading-edge imaging techniques that allow us to make accurate, timely diagnoses. Specialized imaging services include magnetic resonance (MR) spectroscopy, 灌注先生, 先生扩散, 扩散张量成像, MR-ultrasound image fusion for biopsy guidance and direct MR-guided biopsy.

以团队为基础的治疗: Our team is made up of multiple subspecialized experts, including those in genitourinary radiology, medical physics and imaging informatics. We work closely with referring physicians to address specific, individualized concerns.

研究重点: The imaging experts at 皇冠hga025大学洛杉矶分校健康 are dedicated to research. We continually study and develop new techniques, 为患者提供最新的, 最有效的选择.

我们治疗的前列腺疾病

Our prostate imaging team evaluates and diagnoses conditions affecting the prostate, the small walnut-shaped gland that produces seminal fluid. 我们诊断和治疗:

前列腺增生(BPH): Age-related enlargement of the prostate gland. 随着前列腺变大, it may partially block the urethra (the tube that moves urine from the bladder out of the body), 引起下尿路症状.

前列腺癌: 始于前列腺的癌症. It’s the second-leading cause of cancer death in American men.

我们提供的测试和程序

We use a range of advanced tools and tests to assess and treat prostate conditions. 我们的放射科医生可以使用:  

前列腺癌MRI

This imaging test uses magnets, radio waves and a computer to view inside the body. MRIs show us the size and location of tumors, allowing us to:

• 评估治疗效果
• 癌症的诊断和分期
• Follow up on rising PSA levels after prostate removal, which may indicate the cancer has come back 
• Monitor for changes in patients with low-grade prostate disease (active surveillance)
• Pinpoint where to obtain tissue samples for biopsies, which evaluate prostate tissue for cancer cells
• Plan treatment, such as surgery or radiation therapy

在某些情况下, patients may receive an endorectal coil, a thin wire placed in the rectum close to the prostate. This coil can help us view the prostate in more detail. It also allows us to perform MR spectroscopy, which gives us more information about the chemical makeup of prostate cells. 扫描后取出线圈.

We may also use MRI to evaluate the blood flow (灌注先生) or extent of cellular crowding (先生扩散). These newer techniques can identify subtle changes to help us better detect and stage prostate cancer. 例如, blood flow increases in cancer cells, and cellular crowding is worse where cancer cells are rapidly turning over.    

前列腺动脉栓塞术(PAE)

This nonsurgical procedure is performed to improve lower urinary tract symptoms, 比如尿失禁, 由前列腺增生引起. An interventional radiologist guides a catheter to the arteries that supply the prostate gland. Then they inject tiny particles into the arteries to reduce blood supply, shrink the prostate and relieve BPH symptoms.

Transurethral ultrasound ablation (TULSA)

This novel MRI-guided procedure uses ultrasound to effectively treat prostate cancer with minimal side effects. Your physician places a small, rod-shaped device into the urethra. This device has 10 ultrasound-generating elements that can cover the entire prostate gland. A software algorithm tells the elements to send out sound waves that heat and destroy diseased prostate tissue.

The entire procedure takes place in an MRI scanner so your physician can closely monitor the treatment and assess the degree and location of the heating. You can typically return home the same day.
