Chemistry in the Radiologic Sciences.

Chemistry is interconnected with physics and biology. The periodic table of the elements demonstrates the fundamentals of chemistry that underpin the radiologic sciences in a logical and consistent fashion. This article provides an overview to better understand chemistry's function in radiology, including the chemistry of the human body, photoelectric effects, radiation chemistry, radiopharmaceuticals, molecular imaging, and radiation protection.

Persistent pain following lumbar disc replacement.

Background: Pain patterns associated with the facet and sacroiliac joints following lumbar total disc replacement correlate with biomechanical modeling observations, such as load transfer to the posterior spinal elements in total disc replacement with an artificial disc. When conventional treatment options are exhausted, spinal cord stimulation (SCS) offers clinically favorable outcomes to treat intractable pain.

Objectives: To contribute to the literature on neuroaugmentive techniques and on pain following disc replacement, and to highlight recent advances and forward-thinking concepts for nonsurgical intradiscal therapies.

Benefits of inferential statistical methods in radiation exposure studies: another look at percutaneous spinal cord stimulation mapping [trialing] procedures.

Background: Two studies, each consisting of large sample sets, were recently published on radiation exposure in percutaneous spinal cord stimulation (SCS) trialing procedures. A more rigorous use of statistical methods in the second study more accurately defined benchmark reference levels. Principally, one physician implanter-considered an advanced interventional pain physician-performed all such procedures to nullify inter-physician variability.

Spinal cord stimulation to treat postthoracotomy neuralgia: non-small-cell lung cancer: a case report.

Surgery is the mainstay of therapy for resectable-type tumors associated with non-small-cell lung cancer. Today, thoracotomy and video-assisted thoracotomy are surgical options. The prevalence of chronic pain with neuropathic symptoms is relatively high after thoracotomy.

Feasibility of combined epicranial temporal and occipital neurostimulation: treatment of a challenging case of headache.

Background: Evidence of a paradigm shift towards epicranial neurostimulation treatment techniques aimed at the site of headache pain is beginning to populate the literature. This is most apparent by 2 recently published reports describing alternative approaches to peripheral nerve stimulation techniques for refractory migraine, including hemiplegic migraine.

Objectives: To contribute to the emerging literature on epicranial-based neuroaugmentative approaches which target site-specific areas of distinct, but relatively diffuse, headache pain.

Radiation exposure in percutaneous spinal cord stimulation mapping: a preliminary report.

Background: The utilization of spinal cord stimulation (SCS) to treat intractable pain has increased substantially in recent years. Integral to this therapy, the fluoroscope assists with requisite mapping protocols during trialing procedures to identify topographical dermatomal representations of spinal segments, and its use demands measurements of radiation exposure. However, such data is not found in the literature.

Spinal cord stimulation for pain management in ankylosing spondylitis: a case report.

Introduction.  The classic presentation of ankylosing spondylitis not only impairs spinal mobility but also imposes functional limitations, and fatigue is common. Methods.

Chest compressions: biomechanics and injury.

Context: Radiologic technologists are sometimes called on to resuscitate patients in cardiac emergencies. By understanding the dynamics of chest compressions during cardiopulmonary resuscitation (CPR) and the related risks for rib and sternal fractures, R.T.
