This was my first time using Greater Waterbury Imaging Ctr. I was comfortable but scared. And it was tiring. The cardiologist put me on the treadmill. I would continue to use their services because everybody was great! It was also convenient. My daughter took me to my appointment. I was not aware that there was radiation. She had her kids with her. And plus she is pregnant. So they asked her not to come in with me. I did get fast results. I am getting them tomorrow. The results should be good because they didn't call for my appointment. My appointment was two weeks ago. They were easy to schedule with. They got me in as soon as they could. They were super nice, polite, and courteous. I was breathing very heavy because I used the treadmill right before I went in. They didn't offer valium. But I wouldn't have taken any anyway. I usually don't take anything except ibuprofen. I would recommend Greater Waterbury Imaging Ctr to my family and friends.
