Amazing Children's Spect/CT Scanner at UCSF

The colorful, creative environment of the Spect/CT scanner at UCSF Benioff Children’s Hospital makes children feel at ease. The audio and visual stimulation provides a unique pediatric experience that even has some kids asking if they can come back and do it again! Because children feel calm and comfortable, anesthesia does not have to be used as often. Moreover, the technologist is able to focus, making the process safer and more efficient. Jeffrey Geiger gave us tour of the incredible camping-themed room.

BODY RIG Research

1) Multiparametric Prostate MR program (12 patients a week). 
2) Liver MR: for diffuse disease and dietary intervention studies.
3) Body Rig-integrate advance PET and MR imaging for the real time guidance biopsies in treatment and to this end we have been using an  FDA-approved direct MR guided biopsy device that allows for improved identification characterization prostate cancer in individual patients. 

Advantages of CT versus Fluoroscopy

UCSF Radiologist Dr. Dillon: Understanding the advantages of CT guidance over fluoroscopy when treating facet arthropathy.

Facet Injection

Advantages of CT Guided Injections

UCSF Radiologist Dr Dillon describes the use of CT-image guided injections not only allow for precise positioning at the time of the injections but also for more effective injections at harder to reach places.

Early screening is not without risk

UCSF Radiologist Dr. Brett Elicker describes the effect of multiple CT scans and what UCSF is doing to limit the amount of radiation when screened with CT.


How We Reduce Patient Exposure to Radiation

UCSF Radiologist Dr Elicker describes how the UCSF Department of Radiology minimizes patient exposure to radiation associated with CT scans.

What can CT imaging show us?

UCSF Radiologist Dr. Yeh describes what a CT scan is and how CT imaging helps with cancer imaging and cancer diagnosis.

CT scanner was developed by Dr. Hounsfield who realized that we could make a rotational X-rays around the patient. X-rays will be sent through the patient through detectors behind the patients by circling this x-ray source.  Doctors can digitally synthesize a cross-sectional slice through the human body that’s only a few millimeters thick. X-ray will pass through objects that are less dense more easily so air will be black.  

Guided pain relief

UCSF Radiologist Dr. Hess describes how accurate imaging guidance for spine interventions improves diagnosis and aids in back pain reduction.

These procedures are non-surgical procedures in the sense that we don’t use a big knife and we’re not wheeling the patient in the operating room or not knocking you out. All these “surgeries” done through a needle and will inject variety of different medications.

Accurate image guidance for spine interventions improves diagnosis and helps to reduce back pain.

Using Imaging to uncover the real problem

UCSF Radiologist DR. Hess explains why a CT scan imaging guidance helps uncover real source of pain.

Another reason for doing CT it that we have a better idea of what we’re seeing and to come up with alternative diagnoses in real time.
