Today, thousands of people receive medical treatments that couldn’t have been imagined in previous generations. Treatments that were once impossible have become routine practices due to the implementation of new technology that enhances people’s quality of life. Predictably, much of the technology used in medicine has been thought up by doctors, not laymen, but their methods of invention might surprise you. A Dutch physician invented the first dialysis machine in 1943 by employing various household items, including a washing machine! It took years to perfect the equipment, but now it saves the lives of many who are waiting for kidney transplants. The birth of the pacemaker also has an interesting history. In 1930, an American heart surgeon created a device that could deliver electric shocks directly to the heart with a needle. This original pacemaker was operated by hand and was mostly shunned by the medical community. They believed that keeping a damaged heart beating was too unnatural. Fortunately, by 1950s, people conceded that the idea did have merit, and several new and improved models were designed. Since the discovery of X-rays in 1894, doctors have been able to look inside their patients without cutting them open. While traditional X-rays are still important, advancements in medical technology have made it possible to get an even better glimpse inside the human body. One example is the MRI scanner, which creates a 3-D image out of multiple 2-D pictures. With this, minute internal flaws can be easily identified. If an extremely thorough look is needed, patients can undergo a capsule endoscopy, approved by the FDA in 2001. After swallowing a tiny pill-shaped camera, more than 800,000 pictures can be taken inside the patient’s digestive system and wirelessly uploaded to a physician’s computer. The most regularly performed surgery prior to the 20th century was the removal of limbs, and the tools available for this operation were limited to saws and knives. Now there are many more choices that cause considerably less trauma to the body. Endoscopic surgery is one modern procedure that requires minimal recovery time for the patient. During one of these surgeries, a camera and special instruments are inserted into the body through small cuts that are less than an inch long. The surgeon controls the equipment via a connection line and a monitor; it’s almost like maneuvering through a video game! Another contemporary variation in surgeries is the use of lasers to cut the body’s tissue. Although this method is already predominant in eye surgeries, it is currently being tested in other types of operations as well. The benefits of using lasers are that wounds heal more quickly and there are fewer chances of post-surgical infections. Luckily for us, technology is a fundamental part of medicine today and has led to the development of lifesaving techniques. With so much progress in just the last few decades, more impressive medical technology is certain to arise in the future.

How does having an MRI scan differ from taking a traditional X-ray?
- A MRI uses advanced wireless technology.
- B MRI locates and fixes the defects within the body more easily.
- C MRI produces better pictures of a person’s internal structure.
- D The earliest MRI model employed a needle to create 3-D pictures.

請回想一下文章的第三段。當作者提到傳統 X 光與 MRI 的進步時，他特別強調了 MRI 在「成像方式」上有什麼變化？又是如何描述這種變化對觀察「體內微小細節」的影響呢？

恭喜你精準地鎖定了文章的細節，選出了正確答案！這題的核心在於比較不同醫療診斷技術的「成像效果」。
診斷技術的進化
文中第三段明確提到，雖然傳統 X 光（X-ray）至今仍很重要，但醫學進步讓我們能更清晰地觀察（better glimpse）人體內部。MRI 掃描器（MRI scanner）的關鍵優勢在於它能將多張 2D 照片結合成 3-D 圖像，這使得微小的內部缺陷（minute internal flaws）能更輕易地被識別。這正對應了選項 (C) 所說的，MRI 能提供更優質的內部結構圖像。
