I was recently discharged from the hospital with the following diagnosis: Apical left ventricular thinning and low attenuation suggest possible ischemic insult. What does this mean from a stress test? small sized, mildly reduced, fixed, apical perfusion defect consistent with artifact. It means that there: was a slight abnormality on the nuclear images of the test which the reader interprets as most likely related to things unassociated with your heart or heart problems such as large breasts. Myocardial perfusion imaging (MPI) is an important imaging modality in the management of patients with cardiovascular disease. Not exactly normal but also not indicative of a problem to be … Apical thinning. A 47-year-old male asked: There is a medium-sized inferoseptal and a small sized apical defect worse at rest suggestive of soft tissue attenuation and reconstruction artifact. Background: Apical thinning and other image changes at the apex have been described after attenuation correction of myocardial perfusion single photon emission computed tomography (SPECT) studies, but their clinical significance is unknown. This study aims to determine the causes of apical thinning in myocardial perfusion SPECT, often attributed to reduced myocardial thickness at the apex of the left ventricle. Ischemic heart disease vs coronary artery disease. This study aims to determine the causes of apical thinning in myocardial perfusion SPECT, often attributed to reduced myocardial thickness at the apex of the left ventricle. Apical muscular ventricular septal defect. Home > March 2007 - Volume 28 - Issue 3 > 21 Apical thinning – real or artefact? Apical thinning typically results in a fixed perfusion defect in the apical inferior wall and sometimes apical septum that is best viewed on the apical short axis slices and in the mid ventricular vertical long axis slices. Dr. Donald Colantino answered. Ontransmural fixed inferolateral defect consistent with gut attenuation artifact. This finding is more common in a man than a woman, in an overweight patient, and in certain imaging agents such as thallium. Hi. Apical thinning may be mis-interpreted as a distal LAD infarct; but normal wall motion confirms this as an artifact. Methods Both Tc-99m MIBI SPECT-CT and 64-slice … This effect appears to be exaggerated by attenuation correction. Attenuation correction processing appears to exaggerate this effect. This finding is more common in a man than a woman, in an overweight patient, and in certain imaging agents such as thallium. Methods and results: We studied 102 subjects from a multicenter trial of attenuation correction, 46 with angiographic coronary artery … Ischemic heart disease vs coronary artery disease. What Is Mild Fixed Apical Thinning On Stress Test? What is apical thinning artifact. Selected VLA and HLA images show a small fixed apical defect (see arrows) representing apical thinning. Log in to view full text. Theresa64. In some people, thinning may be more prominent than usual and may simulate a perfusion defect. The diaphragm (sheet of muscle that separates the heart and the tummy structures) can sometimes obscure the bottom part of the heart during nuclear stress testing, and could potentially give rise to abnormal stress test result (a defect). False Positive Reactions. Basal vs apical. Although currently there is agreement that reduced apical counts are not a diagnostic indicator, opinions differ over the … The aim of this study was to compare actual myocardial thickness and AC perfusion count to investigate the cause of apical thinning. 0/250. Internal Medicine 61 years experience. Major Subject Heading (s) Minor Subject Heading (s) Artifacts. This phantom study therefore demonstrates that apical thinning is not simply an anatomical feature but can also be an artefact introduced by the use of attenuation correction. Artifacts* False Positive Reactions Dr. Donald Colantino answered. Major Subject Heading (s) Minor Subject Heading (s) Artifacts. It would be like taking your temperature and getting 98.7 rather than 98.6. MPI plays a key role in diagnosing cardiovascular disease, establishing prognosis, assessing the effectiveness of therapy, and evaluating viability. What Is Mild Fixed Apical Thinning On Stress Test? Apical thinning is a well-known phenomenon in myocardial perfusion SPECT, often attributed to reduced myocardial thickness at the apex of the left ventricle. Although currently there is agreement that reduced apical counts are not a diagnostic indicator, opinions differ over the … Not exactly normal but also not indicative of a problem to be … Apical left ventricular thinning. Background and objective: Apical thinning is a well-known phenomenon in myocardial perfusion SPECT, often attributed to reduced myocardial thickness at the apex of the left ventricle. Attenuation correction processing appears to exaggerate this effect. Selected VLA and HLA images show a small fixed apical defect (see arrows) representing apical thinning. Hi. Attenuation correction processing appears to exaggerate this effect. Methods Both Tc-99m MIBI SPECT-CT and 64-slice … Apical muscular ventricular septal defect. 1131 Objectives Decreased apical count in attenuation corrected (AC) myocardial perfusion, namely “apical thinning”, is a well known phenomenon and may induce false-positive perfusion defects. This phantom study therefore demonstrates that apical thinning is not simply an anatomical feature but can also be an artefact introduced by the use of attenuation correction. “Attenuation artifact” observed in a nuclear stress test is due to the reduction in the intensity / strength of signal when it travels through various body tissues of different densities, such as breast tissues, chest wall, and organs under the diaphragm. Apical thinning is a well-known phenomenon in myocardial perfusion SPECT, often attributed to reduced myocardial thickness at the apex of the left ventricle. False Positive Reactions. Basal vs apical. Apical thinning. The apical thinning variant is even more commonly observed during 13 N-ammonia imaging because of the higher spatial resolution of 13 N-ammonia compared to 82 Rb, and fluorine-18 (18 F) labeled perfusion tracers (in clinical development) would be expected to demonstrate apical thinning because of the very high spatial resolution of 18 F. Another normal variant to … 1131 Objectives Decreased apical count in attenuation corrected (AC) myocardial perfusion, namely “apical thinning”, is a well known phenomenon and may induce false-positive perfusion defects. I was recently discharged from the hospital with the following diagnosis: Apical left ventricular thinning and low attenuation suggest possible ischemic insult. Post a free question. However, MPI is a complex process, subject to a variety of artifacts and pitfalls, which may limit its clinical utility. Background and objective: Apical thinning is a well-known phenomenon in myocardial perfusion SPECT, often attributed to reduced myocardial thickness at the apex of the left ventricle. Can you please explain this in layman's terms? Apical thinning. Methods and results: We studied 102 subjects from a multicenter trial of attenuation correction, 46 with angiographic coronary artery … The apical thinning variant is even more commonly observed during 13 N-ammonia imaging because of the higher spatial resolution of 13 N-ammonia compared to 82 Rb, and fluorine-18 (18 F) labeled perfusion tracers (in clinical development) would be expected to demonstrate apical thinning because of the very high spatial resolution of 18 F. Another normal variant to … Video chat with a U.S. board-certified doctor 24/7 in less than one minute for common issues such as: colds and coughs, stomach symptoms, bladder infections, rashes, and … Attenuation correction processing appears to exaggerate this effect. Apical left ventricular thinning. This can be either a normal physiological variant or an artifact produced by varying spatial resolution of the acquired images (higher at the apex because of detector proximity). Ontransmural fixed inferolateral defect consistent with gut attenuation artifact. Background: Apical thinning and other image changes at the apex have been described after attenuation correction of myocardial perfusion single photon emission computed tomography (SPECT) studies, but their clinical significance is unknown. The appearance of the LV apex may vary between patients. Apical thinning may be mis-interpreted as a distal LAD infarct; but normal wall motion confirms this as an artifact. This effect appears to be exaggerated by attenuation correction. Submitted by Jim from Michigan on 03/01/2017. Can you please explain this in layman's terms? “Attenuation artifact” observed in a nuclear stress test is due to the reduction in the intensity / strength of signal when it travels through various body tissues of different densities, such as breast tissues, chest wall, and organs under the diaphragm.
