概括

聊天GPT与GPT-4V (视力) 显示识别和解释核医学图像的能力有限. 虽然它可以识别一些检查,其准确性和一致性是不可靠的临床使用.

科学领域:

人工智能在医学中的应用
医学成像分析医学成像分析
核医学是一种核医学.

背景情况:

像GPT-4V (视觉) 这样的大型多式模式集成文本和图像数据.
它们在专门的医学成像领域的表现,如核医学,需要进行系统的评估.

研究的目的:

评估ChatGPT与GPT-4V (视觉) 在识别和解释常见的核医学图像方面的能力.
评估GPT-4V的准确性,一致性和可靠性,用于核医学图像分析.

主要方法:

通过ChatGPT使用GPT-4V (默认和高级数据分析版本) 分析了15张核医学图像 (光学图像和PET).
人工智能被要求识别检查类型,追踪器,解释发现,检测异常,并标记相关区域.
三名核医学医生对反应的适当性进行了评价.

主要成果:

默认GPT-4V (视觉) 版本在53%-60%的案例中正确识别了检查和标记物,并在33%-47%的案例中提供了适当的描述.
"高级数据分析 (beta) "版本在90%以上的任务中失败了.
在73%的试验中 (默认) 和87%的试验中 (高级数据分析) 观察到重大不一致.

结论:

GPT-4V (视觉) 在分析核医学图像方面表现出新生的能力.
可靠性的重大限制,包括正确性,可预测性和一致性,排除了其当前的临床应用.

Imaging Studies II: Positron Emission Tomography and Scintigraphy

Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.
Fundamental Principles of PET

Positron Emission Tomography

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
